Is the integer k divisible by 4?
(1) 8k is divisible by 16 --> \(\frac{8k}{16}=\frac{k}{2}=integer\) --> \(k\) is a multiple of 2, but it may or may not be a multiple of 4. Not sufficient.
(2) 9k is divisible by 12 --> \(\frac{9k}{12}=\frac{3k}{4}=integer\) --> in order \(\frac{3k}{4}\) to be an integer \(k\) must be a multiple of 4. Sufficient.
Answer: B

Statement 1: 8k is divisible by 16
In this case, k should have a power of 2, hence it has to be divisible by 2, but we are not sure if it will be divisible by 4
INSUFFICIENT
Statement 2: 9k is divisible by 12
For 9k to be divisible by 12, k should have a power of 3 and a power of 4. Hence it has to be a multiple of 4
SUFFICIENT
Correct Option: B
