This QC question says that t could be any positive integer from 1 to 50. As the solution video says, if t=1 then A=1/2 which is less than B=40. But if t=50 then A is greater than B.
So, we have a case where A>B and a case where A<B. But the answer choice showed as correct in the solution video is A:(A>B)
Shouldn’t the correct option be D?
