given answer is correct it does not provide VM level information whether packets ar allowed or denied , it go upto the Virtual network elvel only and they are suggesting to use Network Watcher before 29 February 2024 Starting 1 July 2021, you will not be able to add new tests in an existing workspace or enable a new workspace in Network Performance Monitor. You can continue to use the tests created prior to 1 July 2021. To minimize service disruption to your current workloads, migrate your tests from Network Performance Monitor to the new Connection Monitor in Azure Network Watcher before 29 February 2024. You can use the Azure ExpressRoute Monitor capability in Network Performance Monitor to monitor end-to-end connectivity and performance between your branch offices and Azure, over Azure ExpressRoute. Key advantages are: Autodetection of ExpressRoute circuits associated with your subscription. Tracking of bandwidth utilization, loss and latency at the circuit, peering, and Azure Virtual Network level for ExpressRoute. Discovery of network topology of your ExpressRoute circuits.

B is correct as To analyze traffic, you need to have an existing network watcher, or enable a network watcher in each region that you have NSGs that you want to analyze traffic for. Traffic analytics can be enabled for NSGs hosted in any of the supported regions.

Although Traffic analytics performs a similar function, it collects and analyzes data from NSG flow logs alone. It can't be the solution to the preamble.

No. Azure traffic manager checks activity in cloud networks only. Here you have VM on-prem and on Azure.

Yes is correct Answer here. Yes, you can use this solution as well. This solution can provide much more in terms of analysis of network traffic. If you just want a simple solution to understand blocked traffic, you can use the IP flow verify tool.
