What notation describes elements of a set that are listed between braces?

The correct answer is roster notation because it specifically refers to the way of representing a set by listing all its elements within braces. For example, if we have a set of fruits, it can be expressed as {apple, banana, cherry}. This representation clearly shows each individual item contained in the set.

Set notation encompasses broader concepts and may describe various ways to express sets, which can include roster notation as a special case. Interval notation, on the other hand, is used primarily to represent ranges of numbers rather than individual elements, such as [1, 5] for all numbers between 1 and 5 inclusive. Enumeration notation is less commonly used in mathematical contexts and typically refers to specifying elements sequentially without the focus on a set structure.

Therefore, the clarity that roster notation provides in listing all elements distinctly is what makes it the correct choice here.
