The answer is E as n/k can be a fraction.
eg.
8*2=16
4*8=32
16/32=0.5

we have to find n/q:

S1-nothing about k
S2- nothing about n.

combined: n=8a and k=4b so

n/k= 8a/4b= 2a/b so n/k= 2a/b if a and b are 2 and 2 the answer is yes=2*2/2=2 (n/k is even) but if a and b are 3 and 2 then 2*3/2=3 (the answer is no. 3 is odd)
