While working on an Hyperledger Fabric app, the user writes a node.js server in the index.js file.Which of the following syntaxes should be used here to create a server over port 3000?let port = process.env.PORT || 3000;<br /> app.listen(port, () => console.log(‘port for server listening is ${port}….’));let port = process.sys.PORT || 3000;<br /> app.get(port, () => console.log(‘port for server listening is ${port}….’));let port = process.sys.PORT && 3000;<br /> app.listen(port, () => console.log(‘port for server listening is ${port}….’));let port = process.env.PORT && 3000;<br /> app.get(port => console.log(‘port for server listening is ${port}….’));

Which line of code starts the server listening on the specified port?config.portportapp.listen(port, () => {...})console.log(`Server is running on port ${port}`)

You are working on a Node.js project and need to temporarily serve a single HTML file named "index.html" on port 3000 using NPX. Which command would you use?1.0 Marksnpx node-server -p 3000 index.htmlnpx serve -p 3000 index.htmlnpx http-server -p 3000 index.htmlnpx start-server -p 3000 index.htmlnpx static-server -p 3000 index.html

How do you start a server listening on port 3000 in Express?app.start(3000, () => { console.log('Server running'); })app.run(3000, () => { console.log('Server running'); })app.listen(3000, () => { console.log('Server running'); })app.launch(3000, () => { console.log('Server running'); })

const net = require('net');  var server = net.createServer((socket) => {    socket.end('goodbye\n');  }).on('error', (err) => {    // handle errors here    throw err;  });  // grab a random port.  server.listen(() => {    address = server.address();    console.log('opened server on %j', address);  });
