Correct answer: B
We know that:
A number is divisible by 11
if difference between the sum of its digits at odd places and the sum of its digits at even places is either 0 or a number divisible by 11.
Given number = 97215k6
So, (6+5+2+9) - (k + 1 + 7) = (14 - k), which must be divisible by 11 ... K = 3
