According to mole concept:

1 mole of an element or compound contains [tex]6.022\time 10^{23}[/tex] number of particles.

The number is called as Avogadro's number.

We are given:

One mole of a copper element

This element will have the Avogadro's number of particles which is [tex]6.02\times 10^{23}[/tex]

Hence, the correct answer is Option c.
