1. (A), (B), (C), (D) and (E)
2. (A), (C) and (D) only
3. (A), (B), (D) and (E) only
4. (B), (D) and (E) only

Correct answer: (A), (B), (D) and (E) only

Solution

Tl3+ is a strong oxidizing agent due to its high oxidation state, Al3+ is stable and does not easily get reduced, Tl+ is indeed more stable than Tl3+, and both Al3+ and Tl+ exhibit high stability in solution.
