The electrical properties and their respective SI units are given below. Identify the wrongly matched pair.

Options

A. `{:("Electrical property", "SI unit"),("Specilic conductance", Sm^(-1)):}`
B. `{:("Electrical property", "SI unit"),("Conductance", S):}`
C. `{:("Electrical property", "SI unit"),("Equivalent conductance",Sm ^(2) g "equiv"^(-1)):}`
D. `{:("Electrical property", "SI unit"),("Cell constant", m):}`

Answer

D

Explanation

Cell constant `= l//a`
Unit `=m//m^(2) =m^(-1).`
