    B is the correct choice.

    ***********

    the plot is V vs T.. and the question is about the slope.

    so let's rearrange the ideal gas law into the form y = mx + b with y = V and x = T

    .. PV = nRT

    .. V = (nR/P) * T + 0

    with slope = n*R/P

    since P is in the denominator, the highest P value gives the lowest slope

    the curve with the lowest slope is curve A and that is choice B
