CWorld

DNo output

Step-by-Step Solution

Solution:

Step 1: Understand method precedence with traits
If a class defines a method with the same name as a trait method, the class method overrides the trait method.
Step 2: Trace the output
Class B has say() returning "World", so calling say() on B's object returns "World".
Final Answer:
World -> Option C
Quick Check:
Class method overrides trait method = "World" [OK]

Quick Trick: Class methods override trait methods with same name [OK]
