The question says even number and a multiple of 3
I will try 2 cases ,
Equal Case:
if n= 72
A would be 6

Not equal Case:
if n = 12
A would be 4

Therefore answer would be D

I hope this helps you

72 is a multiple of 12 so the remainder would be 0.
If we take n=66 then the remainder is 6.
Hence with equal-not equal strategy, the answer is D.

Thanks for the response though.
