Which two languages are commonly used in client scripting? (Choose two.)

The two languages commonly used in client scripting are:

1. JavaScript: JavaScript is the most widely used language for client-side scripting in web browsers. It enables interactive web pages and is an essential part of web applications.
2. VBScript: VBScript, short for Visual Basic Scripting Edition, has been used for client-side scripting, particularly in Internet Explorer. However, its usage has declined significantly with the rise of more modern scripting languages like JavaScript.

The other languages mentioned, Perl, PHP, and Python, are generally used for server-side scripting or general-purpose programming, rather than client-side scripting in web browsers.
