In which of the following haemocyanin pigment is found : -Haemocyanin is a copper-containing respiratory pigment that turns blue when oxygenated. It occurs mainly in molluscs and many arthropods (crustaceans, arachnids).
Annelids mostly have haemoglobin or chlorocruorin (green), dissolved in the plasma; some annelids have other pigments.
As per the answer key, haemocyanin is linked here to Annelida.
(This is doubtful: none of the four options is the usual textbook answer, which is Mollusca or Crustacea.)
So, as per the answer key, the answer is Annelida.
