You need to support the requirements for the Shipping Logic App.

Suggested Answer: C 🗳️
Before you can connect to on-premises data sources from Azure Logic Apps, download and install the on-premises data gateway on a local computer. The gateway works as a bridge that provides quick data transfer and encryption between data sources on premises (not in the cloud) and your logic apps.
The gateway supports BizTalk Server 2016.
Note: Microsoft have now fully incorporated the Azure BizTalk Services capabilities into Logic Apps and Azure App Service Hybrid Connections.
Logic Apps Enterprise Integration pack bring some of the enterprise B2B capabilities like AS2 and X12, EDI standards support
Scenario: The Shipping Logic app must meet the following requirements:
✑ Support the ocean transport and inland transport workflows by using a Logic App.
✑ Support industry-standard protocol X12 message format for various messages including vessel content details and arrival notices.
✑ Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model.
✑ Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.

I was about to settle on S2S VPN connection until I read this: The On-premises data gateway acts as a bridge to provide quick and secure data transfer between on-premises data (data that isn’t in the cloud) and several Microsoft cloud services. These cloud services include Power BI, PowerApps, Power Automate, Azure Analysis Services, and Azure Logic Apps

B. Site to Site s2s VPN Maintain on-premises connectivity to support legacy applications and final BizTalk migrations. I read this as legacy apps need to connect to the BizTalk server in Azure. This is how the work flow starts.

The provided answer is probably correct because you can connect to REST/SOAP services over the Data Gateway using a custom connector. Snip from documentation: "You can also create custom connectors that connect to data sources over HTTP or HTTPS by using REST or SOAP. Although the gateway itself doesn't incur extra costs, the Logic Apps pricing model applies to these connectors and other operations in Azure Logic Apps." https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-gateway-connection#supported-data-sources

Hasn't the VM been already migrated to Azure?

Exactly my first thoughts.. that VM is already in Azure. "The VM has been migrated to a new Standard_D16s_v3 Azure VM by using Azure Site Recovery and must remain running in Azure to complete the BizTalk component migrations"

But as none of the answers suit then, C is the best option. Let's pretend that the VM is on premises.

S2S uses a connection to connect the Vnet to on-premises private network. This does not help in logic app creation. Hence, the given answer is correct

The question does NOT ask if S2S VPN would "help in logic app creation." The question does ask for on-prem connectivity for legacy apps. Data Gateway provides access to on-prem data sources for tools like PowerBI or Analysis Services (which are not needed by the workflow), not legacy apps or support final BizTalk migration. These need general on-prem to VNet connectivity. The answer is S2S VPN.

Your answer is incorrect, the question does ask for on-prem connection to legacy app, see the following text from the question in the shipping logic app part. - Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.

Exactly. Data Gateway does not provide "connectivity to support legacy apps." So it's not the answer. That leaves S2S.

you are right Brak, that would be used in conjunction with Integration Service Environment for Logic apps so to secure them with the on premise VNet

Agreed with "On-premises data Gateway". But what piece of information should I use/consider to discard "S2S VPN" as valid answer?

You shouldn't discard it. See comments from Brak and pieronegri, above. For info on ISE, see https://docs.microsoft.com/en-us/azure/logic-apps/connect-virtual-network-vnet-isolated-environment
