The correct option is B 8
Here,
Divisibility of 8: In a given number, if the number formed with its last 3 digits are divisible by 8 or last 3 digits are ‘0’s then that number is divisible by 8.
Now,
For 28765432, the number formed by last three digits is 432 and it is divisible by 8, hence 28765432 is divisible by 8.
The sum of digits of the given number are not divisible by either 3 or 9, so the number is not divisible by 3 and 9 as well.
