The correct answer is B photoelectric cell and D cathode ray tube.
Farnsworth combined the photoelectric cell and the cathode ray tube to invent the electronic television. The photoelectric cell converts light into an electric signal, while the cathode ray tube is used to display the image on the screen. This combination allowed for the effective transmission and display of images, revolutionizing the way we watch television.
