please select the best answer from the choices provided

Explanation:

A personal idea is original to the writer and doesn't require a citation (which is for others' ideas), a letter from the author isn't needed to identify it, and parentheses are usually for additional information or citations. Starting a new paragraph can signal a shift to one's personal thoughts or ideas.

Answer:

D. A new paragraph
