Which among the following statements is true for conductivity?

Which of the following expressions represents the molar conductivity of an electrolyte of type $A_2B_3$?

Among the following,the plot that correctly represents the conductometric titration of $0.05 \ M \ H_2SO_4$ with $0.1 \ M \ NH_4OH$ is

The molar conductivity of a $0.04 \text{ M}$ $AB_2$ type salt solution at $300 \text{ K}$ is $200 \text{ }\Omega^{-1} \text{cm}^2 \text{mol}^{-1}$. Find the conductivity.

The resistance of a $0.5 \, M$ solution of an electrolyte in a cell was found to be $50 \, \Omega$. If the electrodes in the cell are $2.2 \, cm$ apart and have an area of $4.4 \, cm^2$,then the molar conductivity (in $S \, m^2 \, mol^{-1}$) of the solution is:

$A$ conductivity cell with two electrodes (shaded sides) is half-filled with an infinitely dilute aqueous solution of a weak electrolyte. If the volume is doubled by adding more water at a constant temperature,the molar conductivity of the cell will -
