Option C is correct

Superconductors are the doped semiconductors which are having very low resistance or no resistance to conduct the electricity. Its resistance is directly propotional to temperature.

The resistance does not depends on the quantity of the material such as mass or number of moles, it depends on quality of the material such as the metal used for making the material. Therefore, The resistance of a material is an intensive property  

Thus, scientist observed its intensive properties.
