Node.js offers several compelling benefits for building a backend server, especially for a team already proficient in JavaScript.

1. It includes Node Package Manager (npm), the world's largest software registry, which simplifies the process of incorporating and managing third-party libraries, accelerating development.

2. It allows developers to use JavaScript on both the client and server sides. This unifies the development stack, enabling the team to leverage existing skills and share code, which reduces the learning curve and increases efficiency.

3. Its event-driven, non-blocking I/O model is a core architectural advantage. It allows the server to handle numerous concurrent API requests efficiently without getting blocked by input/output operations, leading to high performance and scalability for web applications.

B. Ensures stability with one major release every few years.

This is factually incorrect. Node.js has a rapid release cycle, with a new major version released approximately every six months, including Long-Term Support (LTS) versions.

C. Performs a static analysis on code before execution to look for runtime errors.

This is incorrect. Node.js executes JavaScript, which is a dynamically-typed language. The V8 engine parses and compiles code, catching syntax errors, but it does not perform static analysis to find potential runtime errors (like type mismatches) before execution.

1. Node.js Official Documentation, "About Node.js": "As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications." This statement supports option E's claim about non-blocking functionality for performance and option D's claim about executing server-side JavaScript.

2. Node.js Official Documentation, "Introduction to Node.js": "Node.js has a built-in package manager called npm, which comes installed with Node.js by default. It helps you manage your project's dependencies." This directly supports option A.

3. Node.js Official Documentation, "Node.js Release Working Group": The official release schedule clearly shows a new major version is released every April and October. This contradicts the claim in option B that major releases occur "every few years."

4. MDN Web Docs, "JavaScript data types and data structures": "JavaScript is a dynamically typed language. This means you don't have to specify the data type of a variable when you declare it... Data types are converted automatically as needed during script execution." This principle explains why the Node.js runtime does not perform the static analysis described in option C.
