Is this appropriate, and why?

ABC Company has a number of projects in progress. The executive of the Health and Safety Training Project is also a member of the project board for two other projects and is very busy. As a result, during this initiation stage, the executive has appointed another person to carry out both their business assurance and the role of change authority for minor and medium severity issues.

Is this appropriate, and why?
A . Yes, because people with delegated project assurance roles may act as the change authority.
B . Yes, because projects that are likely to have many changes should delegate the change authority.
C . No, because the decision to have a change authority should be made before the project is authorized.
D . No, because the project manager identifies the level of tailoring that is relevant for the project.
