A. Slapstick, or physical humor.
Slapstick, or physical humor, is not considered to be one of the major techniques of satire because it is a form of humor that is primarily focused on physical actions and gags, rather than social or political commentary. Satire, on the other hand, typically uses techniques such as irony, sarcasm, and parody to criticize or ridicule societal norms, values, and political institutions. The other three options - deadpan understatement, outrageous exaggeration, and warped logic - are all commonly used techniques in satire, but the precise definition and application of each of these can vary depending on the context and the specific work of satire in question.
