A control’s KeyPress event occurs every time . . . . . . . .

The correct answer is C. The user types a character in the text area.

The KeyPress event occurs when a key is pressed on the keyboard. This event is useful for handling keyboard input, such as entering text into a text box.

The other options are incorrect because they do not cause the KeyPress event to occur. Option A is incorrect because the user selecting a text area does not cause a key to be pressed. Option B is incorrect because the user submitting information in a text area does not cause a key to be pressed. Option D is incorrect because the user tapping the Enter key does not cause a key to be pressed.
