Correct answer: A

Divisible by 6 means divisible by both 2 and 3.
4,326 is even and its digit sum is 15, a multiple of 3 — it passes both.
5,331 is odd; 6,442 (digit sum 16) and 7,258 (digit sum 22) fail the test for 3.

Worth noting

5,331 has digit sum 12 and is divisible by 3, but it is odd, so not by 6.
