hi,

take a look at my original post for more details: https://imat.entermedschool.com/t/imat-2022-question-39/4513?u=juliette

we can rule out option 1) because catalysts would be written above/below the arrow in the reaction, since there is none this reaction doesn’t need a catalyst
this rules out answer A) B) and D)

the rest i’m still not 100% confident in my answer
