TOPIC: Who should PM escalate to if team resource shared with other project in the exam

This is the question I saw but I am not sure which should be the right answer...

You are always struggling with resource supply for your project as they are shared across various projects. Who should you escalate this issue to?

A. HR department
B. PMO
C. Program manager
D. Sponsor

How about functional manager if I am in the matrix / functional organization?

Kenneth,

The key phrase in the question is "various shared projects." That implies (but is not specified) that there is a PMO running the show. That's where I would go to get more resources.

Is the correct answer given?
