    Answer : Option D

    Explanation :

    Correct Option is (B)
    The lower the temperature, the lower the pressure inside of the sphere.
    If the exact values were plotted out, a linear relationship would be apparent.
    Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.
