IMO D
from statement 1
9b is not an even integer tells us b is not even.
b can be a fraction 1/9, 3/9, 5/9, 7/9 or odd integer 1, 3, 5, 7
so statement 1 gives an answer No to the question "is b=6?" Sufficient

From statement 2
4b is not an even integer tells us b is not even.
b can only be a fraction 1/4 or 3/4
so statement 2 gives an answer No to the question "is b=6?" Sufficient
hence D

This one is really testing your language skills, and your ability to determine the total set of possibilities for b.

(1) 9b is not an even integer.
 If 9b is not an even integer, then b cannot possibly be 6, because 9*6 = 54 which is an even integer. Sufficient.

(2) 4b is not an even integer How can 4b possibly be not an even integer if 4 is always even? b must NOT be an integer.
Therefore, b cannot be 6. Sufficient.

Either option is sufficient.

Answer: D
