Solution

The correct option is C $S b H_{3}$
The stability of the hydrides of the particular group decreases down the group as the size of the element in that particular group increases which makes the bond between the element and hydrogen becomes weak, there by it become unstable.
So the correct order of stability of hydrides
$N H_{3} > P H_{3} > A s H_{3} > S b H_{3}$
Hence option D is correct.
