Which pair is wrongly

Solution

 "Allude" means to indirectly or subtly refer to something, usually without explicitly mentioning it. It does not mean to escape from a situation.  "Discrete: Separate" is a correct pairing. "Discrete" refers to something that is distinct, separate, or individually identifiable.  "Gamut: Whole" is a correct pairing. "Gamut" refers to the entire range or extent of something.  "Exacerbated: Increased" is a correct pairing. "Exacerbated" means to make something worse, more intense, or more severe, which aligns with the meaning of "increased."
