(1）n is a factor of 15.
(2) n is a factor of 21.
1) 15= 3*5; as n is a factor of 15 therefore possible values of n are 3 and 5 as n lies between 2<n<6;

hence 1 alone is not sufficient to answer the question.

2) 21=3*7; as n lies between 2<n<6; therefore n must be 3; hence 2 alone is sufficient to answer the question hence B

Correct Answer [spoiler](B)[/spoiler]

2 < n < 6

(1) 15 -> 3,5 HENCE n = 3 OR 5 (Not sufficient)
(2) 21 -> 3,7 HENCE n = 3, because n cannot be larger nor equal to 6
