    Option C is the correct answer.

    Explanation:

    We have charge stored in a capacitor

    Q = CV

    C is the capacitance and V is the voltage.

    A capacitor is connected to a 9 V battery and acquires a charge Q.

    That is

    Q = C x 9 = 9C

    What is the charge on the capacitor if it is connected instead to an 18 V battery

    That is

    Q' = C x 18 = 9C x 2 = 2Q

    Option C is the correct answer.
