C Sharp (C#) - Polymorphism and Abstract Classes

Which statement best describes when to use an abstract class in C#?

AWhen you want to define a common plan without providing full implementation.

BWhen you want to create a fully working class that can be instantiated.

CWhen you want to prevent inheritance altogether.

DWhen you want to create a class with only static methods.

Step-by-Step Solution

Solution:

Step 1: Understand abstract class purpose
An abstract class defines methods or properties that must be implemented by subclasses but does not provide full implementation itself.
Step 2: Compare with concrete class
Concrete classes provide full working code and can be instantiated, unlike abstract classes.
Final Answer:
When you want to define a common plan without providing full implementation. -> Option A
Quick Check:
Abstract class = common plan without full code [OK]

Quick Trick: Abstract = plan only, Concrete = full working code [OK]
