A Hot Penny Is Dropped into Cold Water Inside a Polystyrene

A hot penny is dropped into cold water inside a polystyrene foam cup.Assuming negligible heat loss to the atmosphere and the cup,

A) the decrease in entropy of the penny is equal to the increase in entropy of the water.
∣ ΔS_penny ∣ = ∣ ΔS_water ∣
B) the decrease in entropy of the penny is less than the increase in entropy of the water.
∣ ΔS_penny ∣ < ∣ ΔS_water ∣
C) the decrease in entropy of the penny is more than the increase in entropy of the water.
∣ ΔS_penny ∣ > ∣ ΔS_water ∣
D) the entropy of both the penny and the water increases.
