Good evening, Pineappleman!! Your best answer would be D - Some bacteria are beneficial to human health because it talks about how it helps the process of digesting lactose. Your answer would not be A because it is not raising nor decreasing acidity at all, it is not even talking about the acidity in foods. B is wrong because it does not talk about your liver whatsoever. And C does interfere with digestion, but it not harmful. It does talk about how bacteria can help those with lactose problems digest yogurt naturally. I hope I helped!! Have a great evening.
