Answer 1

The correct choice is (d) Handles unconditional loading

Explanation: The difference between assign method and replace(), is that replace() removes the URL of the current document from the document history, meaning that it is not possible to use the “back” button to navigate back to the original document. When a script unconditionally loads a new document, the replace() method is often a better choice than assign().
