Step-by-step explanation:

The number 28221 is not divisible by the other three options; 2, 6, and 9 because -

1. When the last digit of a number is even then it is divisible by 2. The last digit of the number is odd. Hence, 28221 is not divisible by 2.
2. A number is divisible 6 by when it is divisible by both 2 and 3. The number is not divisible by 2. Hence, 28221 is not divisible by 6.
3. When the sum of all digits in a number is divisible by 9 then the number is divisible by 9. The sum is 2+8+2+2+1 = 15. 15 is not divisible by 9. Hence, 28221 is not divisible by 9.

A number is divisible by 3 when the sum of all digits is divisible by 3. 15 is divisible by 3. Hence, 28221 is divisible by 3.

Option b) 3 is correct.
