Why can't conductors generate static electricity when rubbed together?

a.

a. They do not contain electrons

c. They will direct excess charge to earth

b. They do not have ions

d. Conductors only store charge

Static electricity is due to the temporary transfer of electrons from one material to another throughrubbing their surfaces together. This can only happen with insulated materials because the charge can't spread throughout the materials, so a visible effect can be observed. it c.
