@Shaik Masthan 

In your expalanation you said we are not considering output from third and gate but from third flip flop.

But from diagram it is not clear. It seems like they are taking output from final AND gate.

pls reply

But from diagram it is not clear.

 yes, it is not clearly informed where they are taking the o/p.

But in general we take o/p at FlipFlop, so answered as per that, If it is specified take the o/p at AND gate then we have to consider 3$^{rd}$ AND gate Delay also :)
