What are inserted as cross-reference in Word?

Answer: Option B

Cross-reference in MS Word works like a hyperlink within your document, allowing you to jump from one place to another.

A. Placeholders: These are temporary elements used to hold space for text or graphics but do not create links within the document.

B. Bookmarks: Bookmarks are named locations inside a Word document. When you insert a cross-reference, it can point directly to a specific bookmark. Clicking the cross-reference takes you to that bookmarked location. This makes Bookmarks the correct answer.

C. Objects: These include images, charts, or shapes. While important, cross-references usually point to positions or text, not directly to objects.

D. Word fields: Word fields are codes used for automation (like dates, page numbers, etc.). Cross-references rely on fields internally, but what you actually insert as the reference point is a bookmark.

Therefore, Bookmarks are what you insert and then reference using the cross-reference feature in MS Word.
