C Sharp (C#) - Exception Handling

Given nested try-catch blocks, what happens if an exception is thrown in the inner try and not caught there?

try {
  try {
    throw new Exception();
  } catch (NullReferenceException) {
    Console.WriteLine("Inner catch");
  }
} catch (Exception) {
  Console.WriteLine("Outer catch");
}

AOuter catch block handles the exception

BInner catch block handles the exception

CException is unhandled and program crashes

DBoth catch blocks execute

Step-by-Step Solution

Solution:

Step 1: Analyze inner try-catch
Exception thrown is generic Exception, but inner catch only catches NullReferenceException, so it does not catch it.
Step 2: Outer catch handles exception
Since inner catch does not handle it, exception propagates to outer catch which catches Exception.
Final Answer:
Outer catch block handles the exception -> Option A
Quick Check:
Uncaught inner exception propagates to outer catch [OK]

Quick Trick: Exception bubbles up if inner catch doesn't match [OK]

Common Mistakes:

MISTAKES

Assuming inner catch handles all exceptions
Thinking both catch blocks run
Ignoring exception type matching
