    Answer:

    B and C are correct

    Explanation:

    a) false, pressure increases when volume decreases and temperature increases

    b) true, pressure and temperature are directly proportional

    c) true, pressure and volume are inversely proportional

    d) false, pressure and amount of gas are directly proportional

    all of these relations can be summarized by the ideal gas equation:

    pV = nRT

    p: pressure

    V: volume

    n: amount of substance

    R: gas constant

    T: absolute temperature
