Explanation:

Explanation for the answer C: The AWS Application Discovery Service is a tool designed to help gather information about on-premises applications and their dependencies. In this scenario, the solution architect is facing challenges due to outdated documentation and lack of time from developers to discuss their applications. The Application Discovery Service can be installed on each VM to automatically collect configuration and utilization data. This data can help the architect understand the applications' infrastructure, dependencies, and usage patterns, which is essential for creating an effective migration plan. It is particularly useful in situations where documentation is lacking or incomplete.
Other options are not suitable because:
- Option A: AWS Server Migration Service (SMS) is a service that helps migrate servers to AWS, but it does not collect configuration and utilization data.
- Option B: AWS Migration Portfolio Assessment (MPA) tool is not a standard AWS service, and there is no such tool available in AWS.
- Option D: Registering VMs with AWS Migration Hub does not automatically collect configuration and utilization data; it is used to track migration progress and manage the migration process.
