This isn’t testing reasonableness. This is testing to see if a student understands that to properly compare fractions the wholes have to start as equivalent.
Source: I use questions similar to this every year because if I don’t get some real funky diagrams.
But… you can totally compare fractions without the whole being equivalent. You just have to know the size of the wholes. It’s just a poorly phrased question that has more than one correct answer when only one was intended.
