Answer 1

The Correct Option is D

Concept: A number is divisible by 3 if the sum of its digits is divisible by 3. Explanation: Check digit sums: A: $4+6+7+8 = 25$ (not divisible by 3) B: $5+6+8+7 = 26$ (not divisible by 3) C: $6+9+8+8 = 31$ (not divisible by 3) D: $6+9+8+7 = 30$ (divisible by 3) So, 6987 is divisible by 3.
