Suppose a circular queue of capacity (n −1) elements is implemented with an array of n elements. Assume that the insertion and deletion operations are carried out using REAR and FRONT as array index variables, respectively. Initially, REAR = FRONT = 0. The conditions to detect queue full and queue empty are

(A) full: (REAR+1) mod n == FRONT;    empty: REAR == FRONT

(B) full: (REAR+1) mod == FRONT;    empty: (FRONT+1) mod == REAR

(C) full: REAR == FRONT;                       empty: (REAR+1) mod n == FRONT

(D) full: (FRONT+1) mod n == REAR;    empty: REAR == FRONT
