    A. sag more due to the increase in temperature.

    Explanation:

    Telephone wires sag during hot temperatures due to expansion of the wire and taut during colder temperatures due to contraction.

    Therefore, putting up the wires between the poles, they must be kept slightly loose so that they may not break in due to contraction.

    Therefore, sag of telephone wires are due to the increase in temperature.
