What happens to a markup once it has been flattened?

• A. It becomes a locked object
• B. It remains a markup
• C. Markup becomes part of the page itself, no longer a markup
• D. It is deleted

Answer: (C)

Flattening a markup turns that annotation into part of the page itself. It blends the annotation into the PDF’s content so it’s no longer an independent, editable markup. Once flattened, you can’t select, move, or edit it as a separate annotation in the Markups list. This is why flattening is used when you want to finalize a document and prevent further changes to those markings. If you need to modify later, you’d have to work from an unflattened copy or undo the flatten operation before saving.
