The correct answer highlights three key outcomes that food components can undergo after they have been processed by the body, offering insight into the nutritional and metabolic processes involved.

Storage refers to how the body maintains nutrients such as carbohydrates, fats, and proteins for future energy use. For example, excess glucose can be stored as glycogen in the liver and muscles, while fat is stored in adipose tissue. This process is crucial for maintaining energy balance and ensuring that the body has reserves to tap into during times of need.

Energy production encompasses the metabolic processes that convert food components into energy. Carbohydrates, fats, and proteins are broken down through various biochemical pathways to produce adenosine triphosphate (ATP), which is the molecule used by cells to perform work. This is essential for the body's functioning, supporting everything from muscle contraction to the regulation of body temperature.

Excretion involves the removal of waste products resulting from metabolic activities, such as carbon dioxide and urea, from the body. After food components have been metabolized to extract energy and nutrients, the byproducts must be eliminated to maintain homeostasis and health. Effective excretion helps prevent the build-up of potentially harmful substances in the body.

These processes are fundamental in understanding how the body utilizes nutrients
