Answer – B. (Return blood to the lungs)
The function that capillaries serve in the cardiovascular system is to return blood to the lungs. The capillaries beds are the area where the excess carbondioxide produced by the cells are exchanged with oxygen. The deoxygenated blood is then transported by the capillaries through the circulatory system back to the lungs for reoxygenation

I think check with someone. Being in over your head means that you feel like you've blown things out of proportion or you're speculating but aren't sure about something. Asking someone else for their opinion and advice is really helpful.
A serving of food that has 10 to 19 percent of a nutrient based on a 2000 calorie diet is considered to have a rather imbalanced nutrient portfolio. Although it is also questionable and true what nutrient we're talking about If we're on a high fat diet, having only 10 to 19 percent of carbs for that serving would be considered good.
