if the integer n has exactly 5 positive divisors , including 1 and n , how many positive divisors does √ n have ?
Choose the most appropriate option:	A) 6	B) 5	C) 2	D) 3	E) 4

Rationale: take the example of 16 . . . it has 3 positive divisors ( 1 , 2,4 , 8,16 ) now , take the example of 4 . . . it has only 3 divisors . . so d is the ans
Answer: D
