The answer is the third one: On erythrocytes.

Explanation for each option:

  • On platelets: This is incorrect. Platelets are involved in blood clotting and do not carry A, B, or Rh antigens.

  • Within the plasma: This is incorrect. Plasma is the liquid component of blood and contains antibodies, not antigens. The A, B, and Rh antigens are not located in the plasma.

  • On erythrocytes: This is correct. Erythrocytes, or red blood cells, have surface antigens known as A, B, and Rh. These antigens determine a person's blood type.

  • On leukocytes: This is incorrect. Leukocytes, or white blood cells, are part of the immune system and do not carry A, B, or Rh antigens.

In summary, the A, B, and Rh antigens are located on erythrocytes.
