The specific location of the button may vary slightly depending on the software you are using. Here's how you can locate the button in some common word processing programs:

A. New Comment: In Microsoft Word, you can find the "New Comment" button in the "Review" tab of the ribbon. It is usually located on the far right side of the tab, in the "Comments" section.

B. Compare: The "Compare" button is not related to inserting questions and notes into text in a document. It is typically used to compare two different versions of a document.

C. Research: The "Research" button also does not pertain to inserting questions and notes into text. It is often used to search for additional information or references related to the content of the document.

D. Margins: The "Margins" button is typically used to adjust the margins of a document and does not assist with inserting questions and notes.

Thus, the correct answer is A. New Comment, as it is the button specifically designed for inserting questions and notes into text in a document in Microsoft Word.
