(1) insufficient
(2) insufficient

(1) & (2), n/k

If k = 16, n = 8, n/k is not integer
if k = 8, n = 16, n/k is even integer

=> insufficient

n/k is even integer

1) n=8p does not help since no info abt k

2)k is div by 4 k=4q no clue about n hence insuffi

1) and 2) n/k=2(p/q) => p/q ca be fraction integer hence INSUFFI

IMO E
