c) Hemoerythrin

d) Chlorocruorin

4) Location of the above respiratory pigments are as follows:-

a) Hemoglobin:- Mostly occurs within RBCs or even in blood in suspension

c) Hemerythrin:- Found within coelomocytes which are in turn present within the coelomic fluid

d) Chlorocruorin :- Present in suspension in blood
