Which is an analogy?

An analogy is a comparison between two different things that highlights their similarities in order to explain or clarify a concept. For example, saying "life is like a box of chocolates; you never know what you're going to get" compares life to a box of chocolates to illustrate the unpredictability of experiences. Analogies are often used in literature, education, and everyday conversation to make complex ideas more relatable and understandable.
