The correct answer is:
Aluminium, reacts with excess $\mathrm{NaOH}$ to give $\mathrm{Al}(\mathrm{OH})_3$
Aluminium being amphoteric reacts with aqueous alkalies with the evolution of $\mathrm{H}_2$ gas.
$2 \mathrm{Al}(s) +2 \mathrm{NaOH}(a q)+6 \mathrm{H}_2 \mathrm{O}(l) \longrightarrow 2 \mathrm{Na}^{+}\left[\mathrm{Al}(\mathrm{OH})_4\right]^{-}(a q)+3 \mathrm{H}_2(g) \uparrow$
sodium tetrahydroxoaluminate (III).
$2 \mathrm{Al}(s) +2 \mathrm{NaOH}(a q)+6 \mathrm{H}_2 \mathrm{O}(l) \longrightarrow 2 \mathrm{Na}^{+}\left[\mathrm{Al}(\mathrm{OH})_4\right]^{-}(a q)+3 \mathrm{H}_2(g) \uparrow$
sodium tetrahydroxoaluminate (III).
