well if rise and fall were to be called a compound subject, then why’d they use singular “outcome” in the correct choice ? It should have been plural “outcomes” !! Clearly they’ve used this as a singular subject but used were anyway. So what’s the reason
It can be tricky to deal with singular and plural nouns and verbs in a sentence.
Clearly, the point of this sentence is to communicate that there was one outcome, which was the whole Napoleon saga, which included a rise and a fall. So, the use of the singular "outcome" makes sense.
Thus, the real question becomes that of whether to use "was" or "were," and it's hard to say for sure which is better, though in my opinion "was" is a little better.
So, the upshot is that this question is not a great question because the idea that one choice is better than the others is based on a debatable idea.
