Question

Regarding the hydrides of group 15 elements EH3 (E = N, P, As, Sb), select the correct statement from the following: A. The stability of hydrides decreases down the group. B. The basicity of hydrides decreases down the group. C. The reducing character increases down the group. D. The boiling point increases down the group. Choose the correct answer from the options given below:

(A) A, B & C only
(B) A & D only
(C) A, B, C & D
(D) B & C only
