22. Which of the following is wrongly matched?
(a) Haemoglobin in mammals -RBC
(b) Haemozoin - Plasmodium cytoplasm.
(c) Haemocyanin- Prawn
(d) Haemoglobin dissolved in blood- Pheretima. 

Dear student,
The correct answer is (C).The wrongly matched pair is C in which hemolymph is present in prawns which is analogous to the blood in vertebrates and is present in a body cavity called as haemocoel.Haemocyanin is not present in prawns.
The rest of the options are correct.
a)haemoglobin is a red coloured pigment present in the RBC of mammals and carry oxygen to other parts of the body.
b)Haemozoin is present in the plasmodium cytoplasm which is an malarial pigment.It is found in the RBC of the humans after the malarial infection.
d)Haemoglobin is dissolved in the blood plasma in the Pheretima, hence they appear red in colour.
