    A Capacitance Correct Answer Incorrect Answer
    B Voltage Correct Answer Incorrect Answer
    C Electric field Correct Answer Incorrect Answer
    D Charge Correct Answer Incorrect Answer

    Solution

    When a dielectric is placed between the plates of a capacitor, it increases the capacitance of the capacitor. The capacitance C with a dielectric is given by: C = κC₀ Where κ is the dielectric constant and C₀ is the original capacitance without the dielectric. Thus, the capacitance increases as the dielectric reduces the electric field inside the capacitor, allowing it to store more charge at the same voltage.
