The compound ${\mathrm{K}}_2\left[\mathrm{P}\mathrm{t}\mathrm{C}{\mathrm{l}}_4\right]$ would have a molar conductivity in aqueous solution most closely approaching that of

• A

  $\mathrm{K}\mathrm{N}{\mathrm{O}}_3$
• B

  $\mathrm{C}\mathrm{C}{\mathrm{l}}_4$
• C

  $\mathrm{M}\mathrm{g}\mathrm{S}{\mathrm{O}}_4$
• Correct answer
  D

  $\mathrm{N}{\mathrm{a}}_2\mathrm{S}{\mathrm{O}}_4$

Hence, the correct answer is option: 'D'.
