999, 306, 207, 702, 655

A.

207

B.

306

C.

999

D.

Correct option is D

Logic: A number is divisible by 9 if the sum of its digits is also divisible by 9.
999 → 9 + 9 + 9 = 27 (divisible by 9)
306 → 3 + 0 + 6 =9 (divisible by 9)
207 → 2 + 0 + 7 = 9 (divisible by 9)
702 → 7 + 0 + 2 = 9 (divisible by 9)
655 → 6 + 5 + 5 = 16 (not divisible by 9)
Step 2: Identify the odd one out
All numbers except 655 are divisible by 9.
Correct answer is option (D) (655).
