ATo ensure compatibility with .NET exception handling and serialization
BTo make the exception class abstract
CTo prevent the exception from being caught
DTo automatically log exceptions
Step-by-Step Solution

  3. Final Answer:

    To ensure compatibility with .NET exception handling and serialization -> Option A
  4. Quick Check:

    Standard constructors = .NET compatibility [OK]
Quick Trick: Implement standard constructors for full .NET exception support [OK]
