Suggested Answer:

Box 1: id -
id is a unique identifier for the event.

Box 2: eventType -
eventType is one of the registered event types for this event source.

Box 3: dataVersion -
dataVersion is the schema version of the data object. The publisher defines the schema version.
Scenario: Authentication events are used to monitor users signing in and signing out. All authentication events must be processed by Policy service. Sign outs must be processed as quickly as possible.
The following example shows the properties that are used by all event publishers:
[
{
"topic": string,
"subject": string,
"id": string,
"eventType": string,
"eventTime": string,
"data":{
object-unique-to-each-publisher
},
"dataVersion": string,
"metadataVersion": string
}
]

Wow MS, id and eventType I get but we then have to decide between dataVersion and metadataVersion and somehow know that metadataVersion only has a getter??? Another wonderful question.

Why does the order matter for the 3 values? Isn't this just a class model/interface?

Order does not matter and as long as you do not select duplicates, you get at least 2/3 points. Strange question.

As shown in the example in the explanation of the answer, all 4 values are needed BUT from programmer stand point... ID should not be public and have getter and setter... it should be a private immutable value... so in my opionion it should be eventType dataVersion and metadataVersion (i am not 100% sertain of that answer)

I think answer is correct because id is a required field in EventGrid Schema and if you loog at the EventGridEvent class from Microsoft libraries the property has both getter and setter methods defined. https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.eventgrid.models.eventgridevent.id?view=azure-dotnet#Microsoft_Azure_EventGrid_Models_EventGridEvent_Id
