Correct answer
Explanation
TSpeedButton is specifically designed to function as a toggle button that can remain in a depressed (clicked) state. This is controlled through its GroupIndex property - when multiple TSpeedButtons share the same GroupIndex value, they act as radio buttons where one stays depressed. TButton and TBitBtn are standard push buttons that always return to their normal state after being clicked. TDepressedButton does not exist in the VCL component library.
