Answer is Wrong!
Answer is Right!
The correct answer is C. MessageBoxIcon.Exclamation.
The MessageBoxIcon.Exclamation constant is used to include the Exclamation icon in a message box. The Exclamation icon is a yellow triangle with an exclamation point in the center. It is used to indicate a warning or caution.
The other options are incorrect. MessageBox.exclamation is not a valid constant. MessageBox.Iconexclamation is a typo. MessageBoxWarning.Icon is a valid constant, but it does not include the Exclamation icon.
