The reasoning behind why cooking food in a microwave without rotation is not a requirement relates to the nature of how microwaves heat food. Microwaves cook food by causing water molecules to vibrate, which generates heat. This process can lead to uneven cooking, creating hot and cold spots within the food item.

To ensure that food is cooked evenly and safely, it is generally recommended to stir or rotate the food at least once during cooking. This practice helps redistribute heat, reducing the risk of foodborne illness by ensuring that every part of the food reaches a safe temperature, typically 165°F for many types of food.

Covering food during microwave cooking helps to retain moisture and can also minimize the risk of splatters, which is beneficial for maintaining a clean cooking environment. Thus, while it is advisable to stir or rotate food and cover it during cooking, cooking without rotation is not a mandated practice for microwave cooking, making it the correct choice for this question.
