Solution

The correct option is A If the question can be answered by anyone of the statements alone, but cannot be answered by using the other statement alone.
If V is a perfect square, V+1 will not be a perfect square, i.e it can be answered by the second statement.
But divisibility by 16 does not determine anything.
Hence the answer is A
