Since a ≠ 0, greatest possible value for b will be less than 12 but closer to it.

So it lies between 11 and 12

B

thank you. I failed to take into consideration non-integer values...

To determine the *greatest* possible value b, we should test values as close to 12 as possible (since a=0 and b=12 is not allowed). The question doesn't say b must be an integer, so we can try the square root of 143. That equals ~11.9--put another way, 11<b<12. Going through the answers:

A) Incorrect. b is less than 13.
B) Correct. Since 11<b<12, then it follows that 3<b<12.
C) Incorrect. b is greater than 11.
D) Incorrect. b is greater than 10.
E) Inccorect. b is greater than 9.
