How should you store herbicide?

Herbicides are chemical compounds used to kill unwanted plants or weeds. When storing them, it is important to consider safety precautions and environmental factors. Option A is the correct answer because storing herbicide downwind and downhill from houses, play areas, and ponds helps to prevent the chemical from spreading and causing harm to humans, animals, and the environment. Option B is incorrect because storing herbicides next to human and livestock areas may pose a potential danger to health. Option C is incorrect because storing herbicide on high shelves does not prevent children from accessing it and the lack of signage may result in unintended exposure. Option D is incorrect because an unlocked room does not restrict access to the herbicide, and proper ventilation is not sufficient in ensuring safety.
