(A) Let's assume that b = 8. Using the Pythagorean Theorem, we get that \(6^2\)+\(8^2\) and thus \(c^2\) = 100. Therefore, c = 10.
Of course we know that b is less than 8 which means that c has to be less than 10. SUFFICIENT.
(B) It says that c > 9. This means that c can be e.g. 9.5 (less than 10) or e.g. 20 (more than 10). Thus it is INSUFFICIENT.
A is the answer.
