When Solid Ca(CH₃COO)₂ Is Dissolved in a Nearly Saturated Solution $\Delta$

When solid Ca(CH₃COO) ₂ is dissolved in a nearly saturated solution of Ca(CH₃COO) ₂,the solution becomes warmer.This information indicates that if the temperature of a solution is decreased:

A) " $\Delta$ H will become negative."
B) " $\Delta$ H will become zero."
C) "The solubility of Ca(CH₃COO) ₂ will decrease."
D) "The solubility of Ca(CH₃COO) ₂ will increase.'
E) "The solubility of Ca(CH₃COO) ₂ will not change."
