Answer: (C)

Verified step by step guidance

1. Understand that storage fat, also known as adipose tissue, is a type of fat that accumulates in the body.
2. Recognize that the primary role of storage fat is to serve as a long-term energy reserve. This means it stores energy that can be used by the body when needed, such as during periods of fasting or increased energy demand.
3. Consider that storage fat also provides insulation, helping to maintain body temperature by reducing heat loss.
4. Differentiate storage fat from other types of fat, such as essential fat, which is necessary for normal physiological functions.
5. Acknowledge that while storage fat is important for energy and insulation, it is not primarily involved in the structural composition of cell membranes or the absorption of water-soluble vitamins.
