6² = 36
So, the question is asking "Which of the following is a multiple of 36?"
First off, 36 is EVEN, which means all multiples of 36 are EVEN.
A and B are ODD numbers, so ELIMINATE A and B
Second, 36 is a multiple of 9, which means all multiples of 36 are also multiples of 9.
In other words, the correct answer must be divisible by 9
If a number is divisible by 9, the sum of its digits must be divisible by 9
Check the remaining answer choices...
(C) 52,224
5+2+2+2+4 = 15
15 is NOT divisible by 9, which means 52,224 is NOT divisible by 9
ELIMINATE C
(D) 89,892
8+9+8+9+2 = 36
36 IS divisible by 9, which means 89,892 IS divisible by 9
KEEP D
(E) 92,044
9+2+0+4+4 = 19
19 is NOT divisible by 9, which means 92,044 is NOT divisible by 9
ELIMINATE E
Answer: D
Cheers,
Brent

Or one could have used the calculator and divide each no with 36 to have the remainder as 0.
Which of the option divides completely is the right answer.. option D is the answer.
