The corect answer to the question is NH3 > SbH3 > AsH3 > PH3
The polarity of a bond can rougly be said as directly proportional to the difference in electronegativity between the two species in the molecule.
Here I have arranged the order on the basis of magnitude of difference of electronegativity in the given molecules
 
I hope it Helps!!
