Tin Has Two Common Allotropes at Atmospheric Pressure $\alpha$ -Tin, Is Stable Below a Temperature of 13

Tin has two common allotropes at atmospheric pressure.Gray tin, or $\alpha$ -tin, is stable below a temperature of 13.2 $\degree$ C, and is a dull gray powder with essentially no electrical conductivity.White tin, or $\beta$ -tin, is stable at or above room temperature, and is malleable, silvery-white, and conductive in three dimensions.Which of the following statements regarding these allotropes could be correct?

A) Gray tin adopts a structure similar to diamond.
B) Gray tin adopts a structure similar to graphite.
C) White tin is composed of clusters similar to fullerenes.
D) White tin adopts a structure similar to diamond.
E) None of these are correct.
