    Correct Answer
    A. X-ray tube
    Explanation
    The conversion takes place in the X-ray tube. The X-ray tube is a device that generates X-rays by converting electrical energy into X-ray radiation. It consists of a cathode filament and an anode target, which are housed within a glass envelope. When the filament is heated, it emits electrons that are accelerated towards the anode target. The collision of the electrons with the anode target results in the production of X-ray photons, which are then emitted from the X-ray tube. Therefore, the X-ray tube is the location where the conversion of electrical energy into X-ray radiation occurs.
