The answer is D.
If n = 5:
Qty A = q^0 = 1
Qty B = q^1 = q
--> We do not know whether q > 1.
If n = 10:
Qty A = q^5
Qty B = q^2
--> If q = 1, then q^5 = q^2, otherwise q^5 > q^2. Again, we do not know the value of q.
We will keep getting different answers for different values of n. Therefore, we will not get a unique answer.
