Electric current is to be passed from one body to another. For this purpose, the two bodies mbst be joined by I
$(a)$. cotton thread
$(b)$. plastic string
$(c)$. copper wire
$(d)$. rubber band

Academic Physics NCERT Class 8

The two bodies must be joined with a good conductor of electricity through which the current may pass easily.

Copper is a good conductor of electricity.

So, option $(c)$ is correct.
