(A) The hydrides of group $-15$ elements are $NH_3, PH_3, AsH_3, SbH_3,$ and $BiH_3$.These hydrides act as Lewis bases due to the presence of a lone pair of electrons on the central atom.As we move down the group,the size of the central atom increases,and the electron density on the lone pair decreases.Consequently,the availability of the lone pair for donation decreases,making the basic strength decrease down the group.Therefore,$NH_3$ is the most basic hydride among them.

Which element of group $-15$ forms the most basic hydride with hydrogen?
