Which statement describes the liquid portion that remains after blood has clotted?

Explanation:
The liquid left after blood has clotted is serum. When blood clots, the clot forms and traps cells, leaving a clear liquid that contains water, electrolytes, antibodies, and other dissolved substances but no fibrinogen or other clotting factors, which were used up in the clot. Plasma is the liquid from unclotted blood and still contains those clotting factors. Red blood cells and platelets are cellular components, not the liquid portion. So the description that fits is the liquid portion of clotted blood.
