Statement 1
(1) 6 is a factor of n^2
As n is an integer, if 6 is a factor of \(n^2\), 6 is a factor of n.
Note, we are able to conclude this because n is an integer.
Hence, the statement is sufficient. We can eliminate B, C and E.
Statement 2
(2) 6 is a factor of 2n
This statement is not sufficient.
Ex.
n = 3, 6 is factor of 2n (i.e. 6), but 6 is not a factor of 3.
n = 6, 6 is a factor of 2n (i.e. 12), and 6 is a factor of 6.
