Question

Which of the following cannot be included as a component of plasma?

• A. RBC
• B. WBC
• C. Platelets
• D. All of the above

Answer 1

The correct option is D All of the above

One half of blood is composed of red blood cells (RBC), white blood cells (WBC) and platelets which are considered as solid part of blood and another half of blood is composed of water, salts and proteins which is the fluid part of blood. The fluid part of blood is known as plasma. Hence RBC, WBC and platelets cannot be included as a component of plasma.

So, the correct answer is 'All of the above'.
