a) Only I and II are correct.
b) Only II and III are correct.
c) Only III and IV are correct.
d) Only I and IV are correct.

The correct alternative is "d) Only I and IV are correct." The tube with citrate sodium is used to collect blood samples for coagulation tests, and it contains an anticoagulant that prevents the blood from clotting. The citrate sodium also inhibits the enzymes of the glycolytic pathway and prevents erythrocytes from metabolizing glucose while the total blood is transported to the laboratory.
