    Solution:
    Answer will be (a)
    Reason:
    According to Fourier's law of conduction
    q = - k* (∆T/∆X)
    Where q is the heat transfer per unit area
    ∆T/∆X = Change in temperature with distance
    k ...

    Solution Summary

    The solution contains a detailed explanation as to how to compare the conductivities of two separate materials from a plot comparing temperature and distance.
