Practice test question confused

[twiceasfastasyou]

I had stumbled on a recent practice test question from the famous line of 'Crack the SAT' books by Princeton Review. I won't state the question word for word, but the question did ask something like this...

How many numbers from 1 to 100 inclusive are equal to the square of an integer?

A) One
B) Two
C) Three
D) Four
E) Five

Could someone please re-state or evaluate this question so that I may better understand it? It was the only practice test question I had answered wrong, from the 1st of 4 practice tests.

Sincere thanks in advance!

The answer is E imo.

I just restated the question a bit differently, to avoid copyright issues, or anything as such, but I get your solution, thanks for the reply!

I could be mistaken, but wouldn't the list of possible #s be:

1
4
9
16
25
36
49
64
81
100

making it 10?
