Node.js - Cluster Module

What is wrong with this cluster code snippet?

const cluster = require('cluster');
if (cluster.isPrimary) {
  cluster.fork();
} else {
  console.log('Worker running');
}

Acluster.isPrimary is deprecated, should use isMaster

BNo call to cluster.fork in the worker process

CMissing server code inside worker

DNo error, code works fine

Step-by-Step Solution

Solution:

Step 1: Check cluster usage
The primary forks one worker, which only logs a message but does not start a server.
Step 2: Identify missing functionality
Without server code, the worker does not handle requests, so the cluster setup is incomplete.
Final Answer:
Missing server code inside worker -> Option C
Quick Check:
Worker must run server code to handle requests [OK]

Quick Trick: Workers need server code to handle requests [OK]
