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
