Is an immediate response required when a 5-year-old child is home alone?

An immediate response is required when a 5-year-old child is home alone. This is because young children do not have the maturity or skills to handle emergencies on their own, such as if they get hurt or if there is a fire. It is important for an adult to be present to ensure the safety and well-being of the child. Option B is incorrect because it implies that it is okay for a 5-year-old child to be left home alone without any adult supervision. Option C may also be incorrect because emergencies can happen at any time, not just during nights. Option D is incorrect because 24 hours is an extremely long time for a young child to be alone and could result in dangerous situations. Therefore, option A is the most appropriate answer.
