Solution
The correct option is A Cockroach
A respiratory pigment is a molecule, such as haemoglobin in humans and other vertebrates, that increases the oxygen-carrying capacity of the blood. Not all animals have red blood. The color of blood depends upon the type of compound or respiratory pigment within the blood that transports oxygen from the lungs to the tissues. Cockroach's blood contains no red blood cells to transport oxygen because its respiratory system is open. This means that cockroach's blood is pale yellow or colourless. Insects (like many other invertebrates) have haemocytes (an equivalent to a red blood cell). They are bluish in colour because of the haemocyanin they contain.
