Is it correct to use "what's," "who's," and "why's," in a single sentence?
Example:
She was perplexed at the "what's", "who's" and "why's" of the situation, so much so that she lost her mental balance.

That sentence reads fine as-is, though I would make one suggestion.
The apostrophe in the "what's" indicates the possessive rather than the plural. You would be better off removing the apostrophes; eg "whys" instead of "why's".
