Question:

Which of the following is correct?

A You are working in a weak matrix organization and are in the Executing phase of the project.

Explaination

The title of project coordinator indicates this is a weak matrix organization and that you are working within one of the business units rather than under the PMO (as you would if you were in a strong matrix organization). The question also states that the work of the project has begun, so you are in the Executing phase of the project.
