HI,

The reducing character of hydride of group 15 elements increases from NH3 TO BiH3 because the reducing character depends upon stability of hydride . ${\color{Yellow} }$ ${\color{Yellow} {\color{DarkBlue} }}$ BiH₃ is the least stable (because the size of central atom is greatest & therefore its tendency to form stable covalent bond with small hydrogen atom decreases,as a result the bond strength decreases) in this series , hence reducing character increases
