A. contacts B. coil C. diode D. capacitor
Explanation: The main component of a relay is the coil, which is an electromagnet that creates a magnetic field when an electric current is passed through it. The magnetic field is used to activate or deactivate the contacts, which are the part of the relay that switches the circuit on or off. The contacts are typically made of metal and are separated by an insulating material. The coil and contacts are the two main components of a relay and work together to control the operation of the relay.
