Answer 1

Right answer is (d) focusin and focusout To explain I would say: The DOM Level 3 Events specification standardizes the focusin and focusout events as bubbling alternatives to the focus and blur events. The focusin and focusout events bubble, the focus and blur events doesn’t. That means that you can use the focusin and focusout on the parent element of a form field.
