[CPMT 1982]
Options:
A) Stability of +3 oxidation state
B) Reducing character of hydrides is not a standard term; the correct term is “ionic character” or “covalent character” depending on the context.
C) Electronegativity
D) Acidic nature of the pentoxide

Answer:
Correct Answer: A
Solution:
Stability of + 3 oxidation states decreases on account of inert pair effect. Reducing character of hydrides decreases down the group because bond dissociation energy decreases down the group.
