High molecular weight and high concentration, D. Low molecular weight and low concentration', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Albumin (69000)molecular weight is less compared to globulin(90000-150000) and fibrinogen (340000).80%of osmotic pressure of blood is exeed by albumin since it has highest concentration.
