    There will be 4 injectors in the EFI fuel system.

    Answer: Option D

    Explanation:

    For each cylinder, one injector is needed so a four-cylinder engine will have 4 injectors. Usually, it will be present near the intake manifold. So the port of the Electronic Fuel Injection - EFI needs four injectors in the calculation of one per one cylinder.
