Answer» The CORRECT option is (b) It defers script execution until the PAGE has been rendered For explanation I WOULD say: The defer attribute is a boolean attribute. The script is executed after the page has finished parsing. The defer attribute is used if and only if there is SRC attribute. Defer is for EXTERNAL not internal scripts.
