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: \"GATECS2007Q36\" 
The counter is connected as follows: 
\"GATECS2007Q36\" 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



Answer: (C)

Explanation:

Initially A1 A2 A3 A4 =0000 Clr=A1 and A3 So when A1 and A3 both are 1 it again goes to 0000 Hence 0000(init.) -> 0001(A1 and A3=0)->0010 (A1 and A3=0) -> 0011(A1 and A3=0) -> 0100 (A1 and A3=1)[ clear condition satisfied] ->0000(init.) so it goes through 0->1->2->3->4 Ans is (C) part.
