CTo implement all methods of an interface immediately
DTo allow multiple inheritance of classes
Step-by-Step Solution
Solution:

  1. Step 1: Understand partial abstraction concept

    Partial abstraction means a class has some methods with code and some without (abstract).

  2. Step 2: Identify purpose of partial abstraction

  3. Final Answer:

    To provide some method implementations while leaving others abstract -> Option B

  4. Quick Check:

    Partial abstraction = Some methods implemented, some abstract [OK]
Quick Trick: Partial abstraction means some methods have code, others don't [OK]
Common Mistakes:
  • Thinking abstract class has no methods at all
  • Confusing partial abstraction with full abstraction
  • Believing interfaces provide partial abstraction
