(i) True, $\mathrm{T} \ell^{+}$is more stable than $\mathrm{T} \ell^{3+}$, due to inert pair effect. So $\mathrm{T} \ell^{3+}$ is a powerful oxidising agent.
(ii) True, $\mathrm{E}_{\mathrm{Al}^{3+/ A 1}}^0=-1.66 \mathrm{~V}$. So it is difficult to reduce $\mathrm{A} \ell^{3+}$. So $\mathrm{A} \ell^{3+}$ is highly stable.
(iii) False, as $\mathrm{T} \ell^{3+}$ is unstable
(iv) True, $\mathrm{T} \ell^{+}$is more stable than $\mathrm{T} \ell^{3+}$
(v) True, $\mathrm{A} \ell^{3+}$ and $\mathrm{T} \ell^{+}$are highly stable

The correct statements from the following are : (A) $\mathrm{Tl}^{3+}$ is a powerful oxidising agent (B)…
