A $0.020\mathrm{M}$ solution of a strong electrolyte has conductivity $3.6\times 10^{-3}\mathrm{S}\mathrm{c}{\mathrm{m}}^{-1}$. When it is diluted ten-fold to $0.0020\mathrm{M}$, its molar conductivity is found to be $190\mathrm{S}\mathrm{c}{\mathrm{m}}^2\mathrm{mo}{\mathrm{l}}^{-1}$. The correct statement(s) is/are

1. AThe conductivity of the diluted solution is $3.8\times 10^{-4}\mathrm{S}\mathrm{c}{\mathrm{m}}^{-1}$
2. BOn dilution the conductivity falls by a factor smaller than 10
3. CThe increase in molar conductivity on dilution shows that the electrolyte is weak
4. DIf both solutions are measured in the same cell, the resistance of the diluted solution is about 9.5 times that of the original
