Let's simply quantity A and reduce it as much as possible.
Except for the first \(\frac{1}{a}\) all other 'a' in denominators will cancel out.
Leaving the expression as simply \(\frac{1}{a}\)

When we compare it with quantity B which equals 1.
a could be 1 or a could be 0.5.
If a =1 then Qty A = Qty B
If a = 0.5 then Qty A > Qty B
Therefore the relationship cannot be determined.
The answer is D.
