Whom should a project manager work with to handle the internal political and strategic issues that may affect the project quality?

The correct answer is Project sponsor.

Explanation:

The project owner is the firm or organization working on a project. A project sponsor is a person who is responsible for finding finances for the project. A project leader is generally a senior officer, he/she has the responsibility for the success of the project.  

A Project manager has the responsibility of planning, design, control, and execution of a project.  

Since a project sponsor is held accountable for the success of the project, the manager should work with the sponsor to handle internal political and strategic issues. These issues can affect the quality of the project which in turn can affect project success.
