Choose the most appropriate from the option given below:

Canvas Classes · Accepted Answer

Analysis:

(A) TRUE — Stability of E–H bonds decreases down the group (larger atoms, weaker bonds):  ✓

(B) TRUE — Reducing ability increases down the group (weaker E–H bonds → easier to donate electrons):  ✓

(C) FALSE — It's the opposite:  is the strongest reducing agent (weakest Bi–H bonds), while  is the mildest reducing agent. ✗

(D) FALSE — Basicity decreases down the group: .  is the strongest base (lone pair most available). ✗

Answer: Option (3) — A and B only
