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

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
