Which of the following is the name used for Microsoft's JavaScript implementation?

Explanation:
Microsoft's JavaScript implementation is called JScript. This name was used for the version of JavaScript that ran in Internet Explorer and in Windows Script Host, representing Microsoft's variant of the ECMAScript standard with some vendor-specific features. TypeScript, by contrast, is a separate language from Microsoft that adds static types and compiles to JavaScript; it is not the engine itself. PowerScript isn’t related to JavaScript in this context, and “Script” alone isn’t the branded name for Microsoft's engine. So the best answer is JScript.
