B Correct answer
Explanation

This is the correct match. Chlorocruorin is an oxygen-binding pigment which is found in many annelids. It appears green when deoxygenated, and red when oxygenated. Vanabin is found in the blood of sea squirts. Hemocyanin is found in the blood of molluscs and hemoglobin is the respiratory pigment found in the blood of humans.
