I would say that the best theme to address those key points listed, would be: A. Feeling hopeless is unreasonable when faced with challenges. In other words, we shouldn't feel as if the end of that world is at hand, just because challenges and tests come our way. That is to be expected. Hope that helps.
I believe the answer is 2) Keeps the audience interested even if your complex process is not as engaging as it could be hope this helps :)
Even though synonyms generally share the same meaning, they might not apply in the same context. So, if you want to use one specific word you should do that instead of trying to find a synonym that doesn't quite fit into the context you've established. An example is if you want to use the sentence "I was mad", meaning "I was angry", you could look for a synonym. One synonym is "absurd". However, this is a different type of mad, meaning crazy instead of meaning angry. "I was absurd" has an entirely different meaning than originally intended. This is why you should always double check the contextual meaning of the synonym you want to use.
