You are correct, the answer is B. Correction marks.

Correction marks, also known as proofreaders marks, are symbols or annotations used to indicate changes that need to be made to text. These marks are typically used by proofreaders, editors, or teachers to provide feedback and make corrections.

To identify the correct answer, you can analyze the options and eliminate the ones that are incorrect. Let's review the other options:

A. Proofreaders marks: This is another term used interchangeably with correction marks, so it could potentially be the correct answer.

C. Insertion symbols: These symbols are used to indicate that something should be added to the text, but they don't necessarily reflect changes that need to be made.

D. Preview symbols: This option seems unrelated to indicating changes in text.

By comparing and eliminating the options, you can determine that B. Correction marks is the most appropriate answer.
