A developer has defined an Int32 variable called IntVar.

The method:

Convert.ToBoolean(IntVar)

Converts an integer to a Boolean using .NET conversion rules:

0 → False

Any non-zero value (e.g., 1, 2, -3, etc.) → True

Why is Option B Correct?

Since IntVar = 1, Convert.ToBoolean(1) returns True.

This follows standard .NET conversion logic.

Example Execution:

Log Message = Convert.ToBoolean(1)

Output:

True

Why Other Options Are Incorrect?

A (False is displayed) ❌

Incorrect. Only 0 converts to False.

C (System.ArgumentNullException) ❌

Incorrect. This exception occurs when passing null, but IntVar has a valid integer.

D (System.InvalidCastException) ❌

Incorrect. Convert.ToBoolean(Int32) is a valid conversion in .NET.
