I wouldn't worry about this question at all since it deals with a subtle difference between writing "the square root of t" and "\(\sqrt{t}\)". You won't see such question on the real test.

1. t is positive. Square root of t can be either positive or negative. Not sufficient.
2.\(t^2\) is positive and square root of t is a real number.So t should be positive and square root of t can be positive or negative.
Not sufficient.
Combining both statements,we can not proceed further.
Ans : Option E.
