The answer is B. Keep it like a warm coat. A tip when finding similes is to look for phrases such as “like” or “as”, it almost always signals that there is a simile. Since “like” is in the phrase “Keep it like a warm coat”, we can say that it is a simile. As a reference, metaphors do not use key words like “like” and “as”, but compare something to a not humanlike object.
