Step-by-Step Solution
Solution:

  1. Step 1: Understand the role of try-catch

    The try block runs code that might throw an error, and the catch block handles that error.

  2. Step 2: Behavior when error is thrown

    If an error occurs inside try, control moves to catch to handle it, preventing program crash.

  3. Final Answer:

    The error is caught by the catch block if present. -> Option B

  4. Quick Check:

    try-catch error handling = C [OK]
Quick Trick: Errors in try go to catch block if present [OK]
