Step-by-step explanation:
Food should be cooked in the microwave by stirring it at least once during cooking, and then leaving it to stand covered for a minimum of 2 minutes. This allows the heat to be distributed evenly and the food to continue cooking in its residual heat. After cooking, it is important to check the food's internal temperature with a metal stem thermometer to make sure it has reached at least 165º F to ensure it is safe to eat. Option A is the correct answer.
