To determine whether a control is displayed to the user, the user needs to know the property that controls visibility of the control.

Now, let's go through each option and explain why it is right or wrong:

A. Hide: This property is used to hide a control that is visible on the screen. This option does not determine whether a control is displayed to the user.

B. Show: This property is used to make a hidden control visible on the screen. It does not determine whether a control is displayed to the user.

C. Visible: This property is used to determine whether a control is displayed on the screen. If the Visible property is set to true, then the control is displayed. If it is set to false, then the control is hidden. This option is the correct answer.

D. Enabled: The Enabled property determines whether a control can be interacted with by the user. It does not determine whether a control is displayed to the user.

E. Cursor: The Cursor property determines the appearance of the mouse cursor when it is over the control. It does not determine whether a control is displayed to the user.

The Answer is: C
