Can document property fields be inserted anywhere in a document?

Document property fields can indeed be inserted anywhere within a document. This means you have the flexibility to place these fields in various locations based on the needs of your document, whether it be within the body text, headers, footers, or any specific section. Inserting document property fields allows you to automatically display metadata, such as the document title, author, or date, which can update dynamically, making them highly useful for maintaining accurate and consistent information throughout the document. This versatility is what distinguishes the correct answer.

The other options suggest limitations that do not align with the functionality of document property fields, which can be utilized throughout the entire document.
