Node.js - Cluster Module

This Node.js code aims to create two worker processes but has a bug:

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

What is the main problem?

ACalling cluster.fork() inside the worker causes infinite worker creation.

BMissing cluster.isMaster check before forking.

Cconsole.log is inside the master process, so no output.

Dcluster.fork() is not a valid method.

Step-by-Step Solution

Solution:

Step 1: Analyze fork calls in master and worker
Master forks once, but worker also calls cluster.fork(), creating new workers repeatedly.
Step 2: Identify infinite worker creation
Workers keep forking new workers endlessly, causing a loop and resource exhaustion.
Final Answer:
Calling cluster.fork() inside the worker causes infinite worker creation. -> Option A
Quick Check:
Fork inside worker = infinite forks [OK]

Quick Trick: Only master should call cluster.fork() to avoid infinite loops [OK]
