Select the correct statement about follwing reaction:
`"x- sulphur"underset(lt369K)overset(396K)iff "y-sulphur"`
At 369 K both the forms ar stable. This temperature is called transition temperatures

(A) 369 K is considered as transition temperature of sulphur (R ) At 369 K both alpha and beta sulphur are exist in equilibrium
