The correct answer is C) A syntax extension that allows writing HTML in JavaScript.

JSX (JavaScript XML) is a syntax extension for JavaScript that is commonly used with React. It allows you to write HTML-like code directly within your JavaScript, making it easier to create and visualize UI components. JSX ultimately gets transformed into regular JavaScript function calls, enabling developers to build React components with a familiar syntax.
