How many even integers from 1 to 200 (both inclusive) have even number of factors?	Choose the correct choice:
A) 13
B) 14
C) 5
D) 6
E) 7

Rationale: "integers having even number of factors will be perfect squares . even numbers will have even perfect squares . thus , the possible values for the perfect squares are : 4 , 16,36 , 64,100 , 144,196 and the corresponding integers are 2 , 4,6 , 8,10 , 12,14 ( more than 6 ) . thus e is the correct answer ."
Answer: E
