If you were to pick at random it would be 25% given there are 4 options being. However, that isn’t the same as the question about the question, which you see 25% percent twice meaning you could Be randomly right twice actually, so the answer to this question about a question is b.) 50%.

I could see this happening on nexus mods if a mod creator was mad, replaced their mod in an “update” with this and without paying attention you update the mod when prompted by your mod manager
