I have been asked this question by my college director while I was bunking the class.

This interesting question is from Essential JavaScript and jQuery in portion HTML Tables, Javascript & Jquery Basics of HTML

Answer 1

Right choice is (b) number

For explanation I would say: The typeof “infinity” will return number. E.g. typeof Infinity; // it will return “number”, when we divide any number by zero it will generate infinity.
