Answer:
A. We use a citation and formatting style because it's a way to organize and help our readers quickly locate the outside sources we reference.
Step-by-step explanation:
When you quote, in an academic text, you are referring to another text that served as a research source where you extracted relevant and important information for the work you are writing. This is very important to enrich your work and give credibility.
However, you must quote in a specific format, which is necessary for readers of your work to know that the text has citations and to be able to quickly locate the external sources to which you refer.
