Question

What is the difference between a mutex and a critical section in multithreaded programming?

a.

A critical section is process private, while a mutex is not

b.

A critical section is an optimized implementation of a semaphore

c.

A critical section is logically identical to a mutex, but it is implemented in user mode

d.

A critical section is a user-defined counter that defines how many simultaneous owners are allowed on it
