Answer & Solution

Answer: Option Option A

Solution:

To ensure proper document structure when using document.write() in JavaScript, developers can combine it with document.createElement() to create HTML elements dynamically and insert them into the document. This approach allows for precise control over the generated content and ensures that the document structure remains intact. Additionally, using document.write() before or during the document loading process helps avoid issues related to overwriting content or affecting the document's layout.
