Answer: A

Explanation:

Installing dual-flush toilets can significantly reduce indoor water demand. Dual-flush toilets have two flush options: a half flush for liquid waste and a full flush for solid waste. By using less water for liquid waste, these toilets can reduce overall water consumption by up to 30%, helping to achieve the owner’s water reduction goal.
