Which of the following indicates an example in Latin?

The correct answer, "exempli gratia," translates to "for the sake of example" in English. This phrase is commonly used in both Latin and English to introduce specific examples that clarify or illustrate a point being made. In the context of the question, "exempli gratia" serves as a direct indication that what follows is a representation of an example, making it the appropriate choice for identifying an example in Latin.

Other options do not convey the same meaning. "Namely" serves a similar purpose in English, but it's not a Latin expression. "Ut" typically means "as" or "in order to," which does not specifically indicate an example. "Sub," meaning "under" or "below," also does not function as an indicator of examples. Thus, "exempli gratia" remains the clear choice for demonstrating examples in the Latin language.
