View answer and explanation

Correct option: C

\mathrm{NH}_3>\mathrm{PH}_3>\mathrm{AsH}_3>\mathrm{SbH}_3>\mathrm{BiH}_3

Option C (

\mathrm{NH}_3>\mathrm{PH}_3>\mathrm{AsH}_3>\mathrm{SbH}_3>\mathrm{BiH}_3

) is correct because dipole moment decreases down the group due to decreasing electronegativity difference.
