The answer is the fourth one (D): hematocrit.

Explanation for each option:

• Hemostasis: This refers to the process that stops bleeding, which involves the clotting of blood. It is not related to the percentage of red blood cells in a blood sample.

• Hemoglobin: This is a protein in red blood cells that carries oxygen throughout the body. It is not a measure of the percentage of red blood cells in a blood sample.

• Hemolysis: This is the destruction or breakdown of red blood cells, which releases hemoglobin into the blood plasma. It is not a measure of the percentage of red blood cells.

• Hematocrit: This is the correct term for the percentage of red blood cells (RBCs) in a blood sample. It is a measure used to determine the proportion of blood volume that is occupied by red blood cells.

In summary, the percentage of RBCs in a blood sample is called the hematocrit.
