Solution
The correct option is B Skin
The skin of the earthworms feels moist. That is why they are called slimy creatures. The reason behind their moist skin is that earthworm’s breathing organ is their skin. Air can easily pass through the skin of an earthworm. The exchange of gases usually takes place through its moist skin and capillaries. In these regions the oxygen gas is picked up by the haemoglobin dissolved in the blood and carbon dioxide is released out.
