The given figure shows a ripple counter using positive edge triggered flip-flops. If the present state of the counter is $Q_{2}Q_{1}Q_{0}=011$, then its next state $\left(Q_{2}Q_{1}Q_{0}\right)$ will be

  1. $010$
  2. $100$
  3. $111$
  4. $101$

PFA The answer in the attached image :

 

Thus, the sequence is 000 001 010 011 100 101 110 111 and repeat – Asynchronous 3-bit Up Counter.
We are given to start at 011 hence the next state is 100 viz option B.
