Statement 1: n is an integer

if n =6, then k = 2 (integer). YES
if n =1, then k = 1/3 (non-integer). NO. Insufficient.

Statement 2: n/6 is an integer

n/6 = m (where m is an integer)
n = 6m

so,

6m = 3k
k = 2m

since m is an integer, 2m must be an integer. Sufficient.

Choose B

Thanks for your input. However, i think you wanted to say if n=6 not 3.
Trust but verify.
