    a. Thermal-Magnetic
    b. Oil dashpot
    c. Digital/microprocessor
    d. Air Dashpot

    Answer: C. Digital/microprocessor
    Digital and microprocessor-controlled OCPD employ thermal imaging to mimic thermal memory that is characteristic of thermal bi-metal breakers.

    I guessed at this and got it right. I do thermal imagining and I know a microprocessor is needed to process the image.
