Solution

The correct option is A $H C l > C H_{3} C O O H > N a C l > C H_{3} C O O N a$
Since conductance of $H +$ is highest so molar conductivity of HCl will be highest and after that conductance of $C H_{3} C O O H$ will come.

The order of molar conductivities: $H C l > C H_{3} C O O H > N a C l > C H_{3} C O O N a$

Hence, option $A$ is correct.
