The addition of water to calcium oxide (CaO) leads to a chemical change because it results in the formation of calcium hydroxide (Ca(OH)₂), which is also known as slaked lime. This process is an exothermic reaction, meaning it releases heat.
Therefore, the correct answer is:
**B. A chemical change**.
Therefore, the correct answer is:
**B. A chemical change**.
