Step-by-Step Solution
Solution:

  1. Step 1: Understand SSE purpose

    Server-Sent Events send updates one-way from server to browser for real-time data.

  2. Step 2: Identify alternative for two-way communication

  3. Final Answer:

    WebSockets using Flask-SocketIO -> Option C

  4. Quick Check:

    Real-time two-way communication = WebSockets [OK]
Quick Trick: WebSockets enable two-way real-time updates, unlike SSE [OK]
Common Mistakes:
MISTAKES
  • Confusing SSE with regular HTTP requests
  • Thinking static pages can update in real-time
  • Assuming email is real-time communication
