Inheritance through two mutexes

Low task L holds mutex A. Medium task M holds mutex B and is blocked waiting for A. High task H now blocks on B. In an RTOS with full transitive inheritance, what happens to L?

A.L stays at its own low priority the whole timeB.L is raised to H priority, since H waits on M, which waits on LC.L is raised only as far as the priority of MD.L is suspended by the kernel until H has finished
