Which one of the following activities does application management perform?

Defining the physical or geographic location of application vendors is a procurement or business decision and falls outside the scope of Application Management.

The core responsibility of Application Management is to ensure that the required functionality is available within applications to support and achieve the required business outcomes. This includes managing applications from initial requirements through development, testing, deployment, and ongoing operation - acting as custodian of technical knowledge for the applications it manages.

Deciding vendors for storage devices is a Technical Management or infrastructure procurement concern, not a responsibility of Application Management.

Agreeing service levels for services is the responsibility of Service Level Management, not Application Management, even when Application Management supports that service.
