Given below is the diagram of a synchronous sequential circuit with one J-K flip-flop and one T flip-flop with their outputs denoted as A and B respectively, with JA = (Aʹ + Bʹ), KA = (A + B), and TB = A.Starting from the initial state (AB = 00), the sequence of states (AB) visited by the circuit is

A. 00 → 01 → 10 → 11 → 00 .
B. 00 → 10 → 01 → 11 → 00 .
C. 00 → 10 → 11 → 01 → 00
D. 00 → 01 → 11 → 00 ..
Answer» C. 00 → 10 → 11 → 01 → 00
