Arrange the following compounds in the decreasing order of the molar conductivities of their aqueous solutions.
\(\begin{array}{cccc}\mathrm{A} & \quad \mathrm{B} & \quad \mathrm{C} & \quad \mathrm{D} \\ {\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}] \mathrm{Cl}_2\right.} & \quad {\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}_3\right]} & \quad {\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right] \mathrm{Cl}} & \quad {\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right] \mathrm{Cl}_3}\end{array}\)

1. A \(\mathrm{B}>\mathrm{A}>\mathrm{C}>\mathrm{D}\)
2. B \(\mathrm{B}>\mathrm{C}>\mathrm{A}>\mathrm{D}\)
3. C \(D>A>C>B\)
4. D \(\mathrm{A}>\mathrm{B}>\mathrm{D}>\mathrm{C}\)
