Node.js provides two built-in modules for creating servers:

http → creates non-secure HTTP servers

https → creates secure HTTPS servers

A secure server requires:

SSL/TLS certificates (key and cert)

The built-in Node.js module designed to handle these: https

Syntax for a secure server:

const https = require( ' https ' );

const fs = require( ' fs ' );

const options = {

key: fs.readFileSync( ' key.pem ' ),

cert: fs.readFileSync( ' cert.pem ' )

};

https.createServer(options, (req, res) = > {

res.write( ' Secure Server ' );

res.end();

}).listen(443);

Evaluation of options:

A is incorrect: No built-in module named secure-server exists.

B is incorrect: tls provides low-level TLS sockets, not HTTP/HTTPS servers.

C is incorrect: http only creates an insecure server.

D is correct: https is the built-in module required for secure web servers.

JavaScript Knowledge References (text-only)

Node.js exposes built-in modules http and https for server creation.

Secure servers require the https module, which supports TLS/SSL.

The tls module is lower-level and not used for full HTTP servers.
