    (d) all of the above

    Explanation:

    Effect on the density of temperature: If we increase the temperature of any room then particles of the room moves and to and fro and so density is decrease

    Effect on the viscosity of temperature : viscosity is inversely proportional to the temperature if we increase the temperature viscosity decreases and if we decrease the temperature viscosity increases.

    Effect on the resistance of temperature : For metals if we increase the temperature then resistance increases and for semiconductor if we increase the temperature resistance decreases

    So from above discussion all the parameter depends on the temperature so option (d (will be the correct option
