The correct answer is A. AutoSize property.
The AutoSize property determines whether the control automatically sizes to fit its current contents. If the AutoSize property is set to True, the control will resize itself to fit the text that is displayed in it. If the AutoSize property is set to False, the control will maintain its original size, regardless of the text that is displayed in it.
The Control property is a property of all controls that specifies the type of control. The Auto control property is not a valid property. The AutoFormat property is a property of some controls that specifies the format of the control.
