Correct: A
The primary environment where JavaScript runs is web browsers. JavaScript is mainly used for client-side scripting, enabling interactivity and dynamic functionality within web pages. It can manipulate and interact with the Document Object Model (DOM), handle user events, make AJAX requests, and perform various other tasks to enhance the user experience on websites. While JavaScript can also run on servers and interact with databases through platforms like Node.js, its primary role is in web browsers.
