- BIn any capacity endorsed thereon, or in any lower capacity in the same department, or in any capacity covered by a general endorsement✓ correct
- CIn any capacity aboard any vessel, regardless of department

Why B is correct
46 CFR §10.201(b) and §10.205(f) both state that an MMC authorizes the holder to serve in any capacity endorsed thereon, or in any lower capacity in the same department, or in any capacity covered by a general endorsement. It does not authorize service in higher capacities or across departments.
