Choose the correct statements about the hydrides of group 15 elements.
A. The stability of the hydrides decreases in the order
\(\mathrm{NH}_{3}>\mathrm{PH}_{3}>\mathrm{AsH}_{3}>\mathrm{SbH}_{3}>\mathrm{BiH}_{3}\).
B. The reducing ability of the hydrides increases in the order \(\mathrm{NH}_{3}<\mathrm{PH}_{3}<\mathrm{AsH}_{3}<\mathrm{SbH}_{3}<\mathrm{BiH}_{3}\).
C. Among the hydrides, \(\mathrm{NH}_{3}\)is strong reducing agent while \(\mathrm{BiH}_{3}\)is mild reducing agent.
D. The basicity of the hydrides increases in the order \(\mathrm{NH}_{3}<\mathrm{PH}_{3}<\mathrm{AsH}_{3}<\mathrm{SbH}_{3}<\mathrm{BiH}_{3}\).
