Answer selection area is too large!

Maybe it's just me but in exercises, I'm frequently accidentally changing my answer before hitting submit and it's causing me to get things marked as wrong. I sometimes just randomly click in the open space on the page but I can be nowhere near answer selections and those random clicks accidentally change a selected answer without me realizing it and ultimately get them wrong.

For me this isn't a huge deal because I'm just brushing up on skills I haven't used in a long time but it's still frustrating to know I got it right and being marked wrong. I already do that to myself enough when it's typed answers and I miss a key while typing!
