Flip-Flops

Q1: Two J-K flip-flops with their J-K inputs tied HIGH are cascaded to be used as counters. After four input clock pulses, the binary count is ________.

A 00

B 11

C 01

D 10

ANS:A - 00

Since it is cascaded i guess output q from 1st jk flip-flop drives clock of 2nd flip-flop. So if we assume initially q2q1=00.

Then further count sequence will be 11..10...01...00.
