Which of the following is NOT true regarding conditional variable, e.g. x?
A) The only operations that can be invoked on a condition variable are wait() and signal()
B) x.wait() means that the process invoking this operation is suspended until another process invokes x.signal()
C) The x.signal() operation resumes exactly one suspended process
D) If no process is suspended, then the signal() operation still affects the state of the semaphore

A condition variable does not affect the state of a semaphore, so option D is not true. Option A is true because wait() and signal() are the only operations that can be invoked on a condition variable. Option B is true because wait() suspends the process until it receives a signal. Option C is true because signal() resumes only one suspended process.
