You can rationalize your way to exclude all but a last answer, there by making it the right answer.

Like, seeing as there are two 25% options, so there aren't four different answers, which means there isn't a 25% chance. This lead to there only being two options left 50% or 60%. This would seem to make 50% the right answer, but it's not, because you know the options, so it's not random, which in turn means you're not guessing. So you have more that 50% chance of choosing the right answer. So 60% is the closest to a right answer, by bullshitting and gaslighting yourself into thinking you solved question.
