C Correct answer
Explanation

Haemocyanin is a copper-based respiratory pigment found in arthropods and molluscs, unlike vertebrates' iron-based haemoglobin. Copper gives haemocyanin a blue color when oxygenated, contrasting with haemoglobin's red color. Cockroaches utilize haemocyanin for oxygen transport in their hemolymph.
