Mistaken Reversal versus Mistaken Negation

Ashley2018-1

Aren't the two logical equivalents? Mistaken Reversal is "confusing Necessary for Sufficient" while it's the other way around for Mistaken Negation. If the answer choice states "confusing Sufficient for Necessary" and the premise contains a mistaken reversal, is that still the correct choice? This has been bothering me a lot.

I'd also add that technically a mistaken negation (given A→B) is anything that isnt A←some→/B.

No, I get that but in the question I was doing, it had R--->C in the premises and it concluded C--->R. I thought that was a Mistaken Reversal, or a conflation of necessary with sufficient but the correct answer choice had confusing sufficient with necessary, so I was wondering if that meant MR and Mistaken Negation were logical equivalents and therefore the same.

The question I am referring to is from PT22.S2.Q25.

Thanks
I was also attracted to answer choice D; I read the thread and the consensus appears to be that it wasn't describing a flaw at all. Is the conclusion about two beliefs rather than one?
