You are question options units are wrong the unit of resistivity is ohm-m the resistivity of copper is at 20 degree is about 1.07*10^-6 ohm-m.

Resistivity unit is ohm m not ohm. And resistivity of copper annealed is 1.72*10-8 at temp.00393.

Can you explain the calculation of aluminium & copper resistivity?
