Correct Answer: E

This question is looking for a definite yes or no answer. Statement (1) is not sufficient since all it tells us is that t is a positive number. Unless the square root is taken, a positive number has two square roots, a positive root and a negative root. For example, if t is 4, then it has two square roots, 2 and –2. So we can eliminate A and D.
