C#.NET — Interpreting an unhandled exception report: Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array. at CuriousTabConsoleApplication.Program.Main(String[] args) in D:\ConsoleApplication\Program.cs:line 14 Which statements are correct?

Introduction / Context:
Reading exception reports is a core debugging skill. This prompt shows an unhandled System.IndexOutOfRangeException and asks you to identify what definitely happened.

Given Data / Assumptions:

• The exception type is IndexOutOfRangeException.
• The message states the index was outside array bounds.
• The stack trace points to Program.cs line 14.
• The exception is unhandled.

Concept / Approach:
An unhandled exception means the program did not catch that exception type anywhere on the call stack. Execution does not continue normally after an unhandled exception. The stack trace pinpoints the line and call path, and the message describes the condition (invalid array index).

Step-by-Step Solution:

Verification / Alternative check:
Run a small program that indexes past the last element; you will see the same exception type and similar stack trace, and the process will terminate.

Why Other Options Are Wrong:

• B and C include the false claim that execution continued or that the CLR “could not handle” it.
• A is incomplete because 3 and 4 are also correct.
• E is wrong because several statements are correct.

Common Pitfalls:
Confusing “unhandled by user code” with “unhandled by the CLR.” The CLR reports and terminates; it does not silently resume.

Final Answer:
1, 3 and 4 only
