The correct option is D

All of these


For 235x7 to be divisible by 3, the sum of the digits of 235x7 must be divisible by 3.

2 + 3 + 5 + x + 7 = 17 + x must be divisible by 3.

The number from the given options which will satisfy the above condition is 7.

The other options will make the sum = 20, 23, 28, none of which are divisible by 3.

17 + 7 = 24 which is divisible by 3.

7 is the correct answer.
