Mod 12 has 4 FF then output frequency should be 1.25 KHZ. Please anyone explain the answer.

Yes, agree it is 1.25 kHz.

For a binary counter or M mod counter, the output frequency is f/2^n irrespective of the synchronous and asynchronous counter where f is the input frequency n is a number of flip-flops (only if duty cycle =50%).

It's correct .833khz.
Since mod-12 counter is a shortened modulus counter it does not utilizes all the possible states. Therefore it's a divide by N counter.
