    Connections are heavy and expensive to create, while channels are lightweight and designed for reuse.
  2. Step 2: Identify why pooling channels is efficient

    Pooling channels avoids the overhead of creating new connections repeatedly, improving performance.
  3. Final Answer:

    Channels are lightweight and faster to create than connections -> Option C
  4. Quick Check:

    Channel pooling benefit = A [OK]
Quick Trick: Use channels to save resources, not new connections each time [OK]
Common Mistakes:
MISTAKES
