α -sulphur <=>[> 369 K][< 369 K] β - sulphur at room temperature α-sulphur (Rhombic) is most stable form.

Statement I is false but Statement II is true.

Both Statement I and Statement II are true.

Both Statement I is true but Statement II is false.

Roth Statement I and Statement II are false.

α -sulphur >369K<369K​β - sulphur at room temperature α-sulphur (Rhombic) is most stable form.

$α$ -sulphur $> 369 K < 369 K β$ - sulphur

at room temperature $α$ -sulphur (Rhombic) is most stable form.
