I:  Mullikan is scale is bigger than Pauling’s scale

II:  Pauling is scale is bigger than Milliken’s scale

In all the choice given, C is the correct choice

Relation between the Pauling and Mulliken scale of EN

${\text{(EN)}}_{\text{M\hspace{0.17em}}}{\text{=(2.8)(EN)}}_{\text{P}}$          Where ${\text{(EN)}}_{\text{M\hspace{0.17em}}}$=EN   on Mulliken scale

 ${\text{(EN)}}_{\text{P}}$= EN on Pauling scale

Note: Pauling’s scale values are commonly used  values.
