Monitor is an Interprocess Communication (IPC) technique which can be described as
(A) It is higher level synchronization primitive and is a collection of procedures, variables, and data structures grouped together in a special package.
(B) It is a non-negative integer which apart from initialization can be acted upon by wait and signal operations.
(C) It uses two primitives, send and receive which are system calls rather than language constructs.
(D) It consists of the IPC primitives implemented as system calls to block the process when they are not allowed to enter critical region to save CPU time.
