Because the Triple Point of Water Is 273 K, What $\Delta$

Because the triple point of water is 273 K, what must be true of the change in enthalpy and the change in entropy for ice converting to water at this temperature?

A) ( $\Delta$ H/ $\Delta$ S = 273 K)
B) ( $\Delta$ S/ $\Delta$ H = 273 K)
C) ( $\Delta$ H - $\Delta$ S = 273 K)
D) ( $\Delta$ H + $\Delta$ S = 273 K
E) ( $\Delta$ H ) ( $\Delta$ S ) = 273 K)
