Why is well-drained soil useful for plants?
Answer and explanation

In well-drained soil, excess water moves out and air spaces remain between soil particles. This gives roots oxygen for respiration along with the moisture needed for growth. Continuous waterlogging deprives roots of oxygen and may cause rotting, so option B is incorrect. Exam tip: link good drainage with root aeration and prevention of waterlogging.
