Is the prime number p equal to 37?
(1) p = n2 +1, where n is an integer.
(2) p2 is greater than 200.

Is the OA = E?

here is why

A. P= n^2 + 1

that could be more than one number, that could be 17 or 37
so INSUFFICIENT

B. P^2 is greater than 200

once again if p is 17^2 that's great than 200, so is 23^2 so is 37^2. INSUFFICIENT

A and B are no sufficient because either 17 or 37 could be P.

am i right?
