I guess the answer is B !! as it has no relevance and is not an observation !!
Answer:
There are different function performed by carbohydrates in the body like-
Storage: When there is excess glucose present in the body they are stored as glycogen in muscles and liver.
Providing energy: Carbohydrates are the primary source of energy for the cells present in our body.
Carbohydrate helps to spare proteins and lipids and helps in providing polysaccharides for membrane carbohydrates.
The body maintains blood glucose levels through hormones. For example, when the blood glucose level gets high insulin is released in the blood by the pancreas which reduces the blood glucose level by accumulating glucose as glycogen in the liver and muscle.
Glucagon works opposite to insulin and increases the blood glucose level.
