To perform a 100-hour inspection, a mechanic must hold which ratings on their certificate?

Explanation:
A 100-hour inspection is a comprehensive check that covers both airframe and powerplant systems. To legally perform it, a mechanic must hold both ratings—airframe and powerplant—on their certificate. The reason is that the inspection touches items across the aircraft structure and the engine/propulsion systems, and a single-rating certificate only authorizes work within that one area. If someone had only one rating, they wouldn’t be allowed to complete the full 100-hour inspection. So the combined authority of Airframe and Powerplant is required.
