Answer & Solution

Answer: Option Option C

Solution:

document.write() can be used to dynamically load external content in JavaScript by generating <script> tags with external sources dynamically.

However, developers should use caution when dynamically loading external content to ensure security and prevent vulnerabilities such as XSS (Cross-Site Scripting) attacks.
