QC Algebra Medium Question

what is stopping the assumption n=0 ?
If n=0, quantity A and B both are equal and answer is D.
Can anyone help me?

Is 0 positive?

I interpreted the question as “ n positive cubed integers”, denoting “n” as the number of cubed integers, for example 1 positive integer, 0 positive integer, etc.

first “0” positive cubed integers do not make sense, though.
