The range of electrical conductivity $(\sigma)$ and resistivity $(\rho)$ for metals,among the following,is

  • A
    $\rho \rightarrow 10^{-5}-10^{-6} \Omega \text{ m}, \sigma \rightarrow 10^5-10^6 \text{ S m}^{-1}$
  • B
    $\rho \rightarrow 10^{11}-10^{19} \Omega \text{ m}, \sigma \rightarrow 10^{-11}-10^{-19} \text{ S m}^{-1}$
  • C
    $\rho \rightarrow 10^2-10^8 \Omega \text{ m}, \sigma \rightarrow 10^{-2}-10^{-8} \text{ S m}^{-1}$
