Calculate the Change in Entropy of a Large Pail of Water

Calculate the change in entropy of a large pail of water after 200 J of energy is reversibly transferred to the water at 20 $\degree$ C.

A) (-0.733 J.K ^{- 1} )
B) +0.683 J.K ^{- 1}
C) (-0.683 J.K ^{- 1} )
D) +0.733 J.K ^{- 1}
E) (-200 J.K ^{- 1} )
