Q1. Which of the following is not a web browser?
Explanation
A web browser is software used to open and navigate websites on the internet. Mozilla Firefox, Safari and Opera are all web browsers; they render web pages, support links, tabs and web standards. Gmail is different: it is an email service provided by Google. Users may open Gmail through a browser or an app, but Gmail itself is not the browser. Hence Gmail is the item that does not belong to the category of web browsers.
