$M{L^3}{T^{ - 1}}{Q^{ - 2}}$ is dimension of
Resistivity
Conductivity
Resistance
None of these
$M{L^3}{T^{ - 1}}{Q^{ - 2}}$ is dimension of
Resistivity $[\rho ] = \frac{{[R]\,.\,[A]}}{{[l]}}$
${\rm{where }} [R] = [M{L^2}{T^{ - 1}}{Q^{ - 2}}]$
$\therefore $ $[\rho ] = [M{L^3}{T^{ - 1}}{Q^{ - 2}}]$
${\rm{where }} [R] = [M{L^2}{T^{ - 1}}{Q^{ - 2}}]$
$\therefore $ $[\rho ] = [M{L^3}{T^{ - 1}}{Q^{ - 2}}]$
