Correct answer: B

A MOD-16 counter counts from 0 to 15. The current state is 1001 (binary) which equals 9 in decimal.

To reach the maximum count (15) from 9, it takes 6 clock pulses (15 - 9 = 6). The next pulse causes an overflow, resetting the counter to 0000.

Total pulses required = 6 + 1 = 7.
