27.The correct statements about ` NH_(3) ` and ` N_(2)H_(4)`
A) Both `NH_(3)` and `N_(2)H_(4)` are basic in aqueous solution but `N_(2)H_(4)` is stronger base than `NH_(3)` due to the presence of two lone parts on two nitrogen atoms
B) Nitrogen atoms in both `NH_(3)` and ` N_(2)H_(4)` are involved in `sp^(3) `hybridization
C) HNH bond angles in both `NH_(3)` and` N_(2)H_(4)` are same
D) Both `NH_(3)` and `N_(2)H_(4)` can act a reducing agents but `N_(2)H_(4)` is stronger reducing agent than `NH_(3) `
