Why we will used 12 flip-flops in a modulus-12 ring counter?

Please explain me the answer.

It should be 6 ff because there is condition that N<2^n where n is smallest number for flip flop.

In the ring counter n flip-flops are used for the mod-n.

It should be 4ff as per the condition N<2^n. But here in options 6 is the nearst answer.

12 flip flops because ring counter uses states n so here modulus is 12.

For mod-12 counter only 4 FF.
For mod- ring counter 12 FF.
For mod- ring counter 12 FF.

May I known why is it so @Velkuargn. Please explain.

The right answer is 12. Because in ring counter n ff's generate n states. In johnson n ff's generate 2n states. What you guys answering is for mod N counter it needs n ff's (N<=2^n).

Because every register contain a flip flop.
