The role of carbohydrates in animal cells primarily involves storing energy (option C). While carbohydrates can also play roles in cell recognition and signaling through glycoproteins and glycolipids, they do not contribute to synthesizing proteins, developing enzymes, or protecting a cell wall in the same way they do in plant cells (where cell walls are a significant feature).
In animal cells, carbohydrates such as glycogen serve as a form of energy storage, which can be broken down into glucose when needed for energy.
