Which word refers to the act of cutting out or removing something?

The term that refers to the act of cutting out or removing something is "exscind." This word is derived from Latin, where "ex-" means out of, and "scindere" means to cut. Therefore, "exscind" specifically denotes the action of cutting out or eliminating a portion of something, making it particularly relevant in contexts where something is being selectively removed.

The other options do not carry this meaning. "Expostulate" refers to expressing strong disapproval or arguing against something, while "effluvia" pertains to unpleasant odors or emissions. "Enormity" relates to the great size or seriousness of an event or situation, not to the act of cutting or removing. Thus, "exscind" is the only choice that accurately encapsulates the act of removal.
