How many even integers from 1 to 100 (both inclusive) have EVEN number of factors?	Choose the correct option: 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 and the corresponding integers are 2 , 4,6 , 8,10 ( more than 4 ) . thus c is the correct answer .
Answer: C
