Answer

Correct option: A.
$a$ and $b$
Conductivity or specific conductance $k\ ($kappa$).$ It is the conductance of solution kept between two electrodes with $1m^2$ area of cross section and distance of $1m.$ It is the reciprocal of resistivity $(p).$
$\text{K}=\frac{1}{\text{p}}$
$\text{S.I}$ unit of $k=\text{sm}^{-1}$
It depends on the nature of the electrolyte and concentration of the electrolyte.
