How can interfaces help when combining multiple unrelated classes that share some behavior in PHP?

ABy merging all classes into one to share code

BBy defining a common interface, unrelated classes can implement shared methods for polymorphism

CBy allowing classes to inherit from multiple parents

DBy automatically copying methods between classes

Step-by-Step Solution

Solution:

Step 1: Identify problem with unrelated classes
Unrelated classes cannot share code via inheritance but can share behavior via interfaces.
Step 2: Use of interfaces
Interfaces define common methods that unrelated classes implement, enabling polymorphism.
Final Answer:
By defining a common interface, unrelated classes can implement shared methods for polymorphism -> Option B
Quick Check:
Interfaces enable shared behavior without inheritance [OK]

Quick Trick: Interfaces enable polymorphism for unrelated classes [OK]
