DError: Trait conflict

Step-by-Step Solution

Solution:

Step 1: Identify trait conflict resolution
Both traits A and B define say(), so conflict arises.
Step 2: Analyze conflict resolution syntax
Using B::say insteadof A; means B's say() is used, ignoring A's.
Final Answer:
B -> Option B
Quick Check:
Trait conflict resolved = B method used [OK]

Quick Trick: Use insteadof to resolve trait method conflicts [OK]

Common Mistakes:

Expecting both methods to run
Ignoring conflict resolution syntax
Assuming error without resolution
