The correct option is C Lt. Governor
The Union Territories are controlled by the President through an executive, who is selected by him with an appropriate designation. This designation is called either Lieutenant Governor or Chief Commissioner or Administrator. In Andaman and Nicobar Islands, Puducherry and Delhi, the overseer is called Lt. Governor, while in Chandigarh, Dadra and Nagar Haveli, Daman and Diu and Lakshadweep he/she is known as Administrator.
