p = 11m - n.

Let m=3 and n=0, with the result that p = (11*3) - 0 = 33.
Average of m, n and p = (3+0+33)/3 = 12. This is our target.
Now plug m=3 into the answer choices to see which yields our target of 12.
Only B works:
4m = 4*3 = 12.

The correct answer is B.

Another approach:

Average = (m + n + p)/3
Replace p with 11m - n, to get:
Average = [m + n + (11m - n)]/3
= 12m/3
= 4m
= B
