Answer
Correct option: B.
Tin
b
Among the given elements tin ( $Sn$ ) shows the allotropy.
Among the given elements tin ( $Sn$ ) shows the allotropy.
$\beta$-tin (the metallic form, or white tin), which is stable at and above room temperature, is malleable. In contrast, $\alpha$-tin (nonmetallic form, or gray tin), which is stable below $13.2^{\circ} C \left(55.8^{\circ} F \right)$, is brittle.
