    Total max nodes = 5 + 3 = 8 nodes.
  3. Final Answer:

    8 nodes total -> Option D
  4. Quick Check:

    Sum max nodes = 8 [OK]
Quick Trick: Add max nodes from all groups for total max [OK]
Common Mistakes:
  • Adding min nodes instead of max
  • Counting only one group
  • Assuming max is fixed cluster size
