    A) the source is increased by \[50{}^\circ C\]

    B) the sink is decreased by\[50{}^\circ C\]

    C) source is increased by \[25{}^\circ C\]and that of sink is decreased by \[25{}^\circ C\]

    D) both source and sink are decreased by \[25{}^\circ C\]

    Correct Answer: B

    Solution :

    [b] \[\frac{{{T}_{1}}-{{T}_{2}}}{{{T}_{1}}}\] is maximum in case [b].
