365564 In semiconductor, the concentrations of electrons and holes are \(8 \times {10^{18}}\;{m^{ - 3}}\) and \(5 \times {10^{18}}\;{m^{ - 3}}\) respectively. If the mobilities of electrons and holes are \(2.3\;{m^2}\;{V^{ - 1}}\;{s^{ - 1}}\) and \(0.01\;{m^2}\;{V^{ - 1}}\;{s^{ - 1}}\) respectively, then semiconductor is

1 \(n - \)type and its resistivity is \(2.95\Omega - m\)
2 \(p - \)type and its resistivity is \(0.034\Omega - m\)
3 \(n - \)type and its resistivity is \(0.34\Omega - m\)
4 \(p - \)type and its resistivity is \(3.4\Omega - m\)
