Answer :
Pre- means before, e.g preschool means before school. So a prelude comes before it, or precedes it
The correct answer is: Option A. Something that precedes something else.
A prelude is an element that provides an introduction to something else. This can be inferred analyzing the prefix pre-, which means "before". A common place to find a prelude in is at the beggining a book, where the prelude serves as a brief introduction to the rest of the book's content.
