Giving an output frequency of $2^n$ (n=number of flip-flop) requires number of flip-flop.

so in order to divide the frequency we need n flip-flop . Here $2^n$ = 64 =>  $2^n$ = $2^6$

 therefore n=6 is the required number of flip-flop.

Yes..64=2^6

Hence 6 nos flipflops are required for this frequency divider.

64=2^6

Hence SIX nos flipflops are required. Hence the option C is correct.
