The control signal functions of a 4-bit binary counter are given below (where X is “don’t care”):                                       

Clear Clock Load Count  Function
1 X X X Clear to 0
0 X 0 0 No change
0 \(

\uparrow\)

1 X Load input 
0 \(

\uparrow\)

0 1 Count input

The counter is connected as follows:

Assume that the counter and gate delays are negligible. If the counter starts at 0, then it cycles through the following sequence:

(A) 0, 3, 4                             (B) 0, 3, 4, 5
(C) 0, 1, 2, 3, 4                     (D) 0, 1, 2, 3, 4, 5
