What is the primary effect of the ‘defer’ attribute on a script tag in an HTML document?

Accepted Answer

The 'defer' attribute instructs the browser to download the script in the background without blocking HTML parsing. The script then executes only after the document has been fully parsed, maintaining the relative order of deferred scripts. Option B describes the default behavior of scripts without attributes. Option C describes the 'async' attribute behavior. Option D is incorrect because 'defer' triggers before the 'load' event.
