- A Contains red blood cells in similar numbers to blood
- B Has a higher protein concentration than blood plasma
- C Contains much less protein than blood plasma
- D Is transported only by active pumping from a dedicated lymph heart in mammals
Correct answer: C. Contains much less protein than blood plasma
Explanation: Lymph is formed from tissue fluid and has a lower protein content than blood plasma, since large plasma proteins do not readily filter out of blood capillaries into the surrounding tissue spaces.
