Answer:

The correct answer is option D, 11.

Step-by-step explanation:

The given number is not divisible by 5 because, unit place is neither 5 nor 0.

To be divisible by 7, the difference of twice the unit digit and the sum of the remaining digits should be 0 or multiple of 7, which is not in this case.

To be divisible by 9, the sum of digits which is 52, should be a multiple of 9, which is not in this case.
