    Correct Answer: B

    Solution :

    The blood of frog contains a clear liquid plasma in, which various types of blood corpuscles are suspended. The red blood corpuscles or eiythrocytes bear respiratory pigment haemoglobin, that serves to carry oxygen to the tissue. Haemocyanin contians copper and occurs in plasma of crustaceans (e.g..
