This question was posed to me in an interview for internship.

This intriguing question comes from Essential JavaScript and jQuery in section HTML Tables, Javascript & Jquery Basics of HTML

Answer 1

The correct option is (b) $(selector).action()

Explanation: The basic syntax of jQuery is $(selector).action(), $ sign defines access of jQuery, (selector) is HTML element, action() is for the jQuery action that is to be performed. E.g. $(“h1”).hide(), this will hide all the <h1> elements.
