Solution
The correct option is A Cockroach
The haemolymph is the circulatory media in the cockroach. It has a colourless plasma and many corpuscles called haemocytes. No respiratory pigment is found in it. Hence, it does not help in the transport of respiratory gases. Its sole function is to transport various nutrients from one part of the body to the other and to carry nitrogenous waste substances from the tissues to the organ of excretion.
The blood of Earthworm, Frog, Rabbit is red coloured due to the presence of respiratory pigment haemoglobin (a red oxygen-carrying pigment).
So, the correct answer is “Cockroach”.
