What does an idiom represent?

An idiom represents an expression that has a figurative meaning understood by a specific group of people, rather than a literal interpretation of the individual words within the expression. For example, the idiom "kick the bucket" means to die, and if taken literally, it does not convey that meaning. This understanding is often cultural or contextual, making idioms distinct from straightforward language. They add color and depth to communication but require familiarity with the expression to grasp its intended meaning. Therefore, option B accurately captures this concept of idioms.
