Answer & Solution

Answer: Option Option C

Solution:

document.write() is appropriate for generating dynamic content based on user interactions. It allows developers to dynamically create HTML content and output it to the document, providing flexibility in generating content based on user actions such as button clicks, form submissions, or data retrieval from external sources. For displaying static content or updating specific HTML elements, other methods like innerHTML or DOM manipulation are more suitable.
