The correct answer is fats.
Bacon and eggs are animal products, which are high in fats, including saturated, monounsaturated and polyunsaturated fats. Furthermore, both bacon and fried eggs are fried using fats such as oils or butter, further increasing the amount of fat consumed. While fried eggs and bacon also contain a good amount of protein, the fat content is higher, and thus, the largest component of the energy from bacon and fried eggs would come from fat.
