Group 15 elements combine with hydrogen to form hydrides `MH_(3)` . Which is false regarding their properties?

A

A. Bond angle decreases from `NH_3` to `SbH_3` due to increase in size of central atom and decrease in electronegativity

B

B. stability and basic character increases from `NH_(3)` to `BiH_3`

C

c. Reducing agent `NH_(3) lt PH_(3) lt AH_(3) lt SbH_(3) lt Bi_(3)`

D

D. Order of boiling point `PH_(3) lt AsH_(3) lt NH_(3) lt SbH_(3) lt BiH_(3)`
