1. \(\sqrt{k} < 16\), so k<256. It can be any number. - Not Sufficient
2. k is divisible by 16.[/quote], 224 is divisible by 16, the next is 240, and the next is 256, but 224 and 256 are not in the range, so only 240 can be that number - Sufficient

Hello
Your explanation is fine, but when second statement is sufficient to answer the question, and not first, then we mark the answer as B.
