Explanation
The Account Manager Target object represents a target created by an account manager for a fiscal year, measure, and target value1. To measure the account managers on a CSAT target, the admin should add a picklist value on the Measure field with Label = CSAT and add Measure Type = Other, on the Account Manager Target object. This way, the account managers can create and assign targets for the CSAT measure to their direct reports2. The other options are incorrect because they either use the wrong object, field, or value for the CSAT target.
