Solution

The correct option is B 76520

Divisibility by 2: A number is divisible by 2 if the digit at the ones place is an even number.

Divisibility by 5: A number is divisible by 5 if it ends with 0 or 5.

Divisibility by 10: All numbers ending with 0 are divisible by 10.


Let's check the divisibility by 2, 5, and 10 for each of the above codes.

Thus, the correct answer is 76520.
