Why does Node.js use the WebSocket protocol (ws://) for Chrome DevTools debugging connections?

ABecause WebSocket allows full-duplex communication needed for interactive debugging

BBecause WebSocket encrypts all data by default

CBecause WebSocket is the only protocol supported by Chrome

DBecause WebSocket automatically restarts Node.js on disconnect

Step-by-Step Solution

Solution:

Step 1: Understand WebSocket role in debugging
WebSocket supports two-way communication, essential for sending commands and receiving data interactively.
Step 2: Evaluate other options
WebSocket does not encrypt by default, is not the only Chrome-supported protocol, and does not restart Node.js automatically.
Final Answer:
Because WebSocket allows full-duplex communication needed for interactive debugging -> Option A
Quick Check:
WebSocket enables interactive two-way debugging [OK]
