A: Chitinous exoskeleton is a characteristic feature of arthropods.
R: It allows diffusion of water vapour from the atmosphere to the body.

The assertion A is correct. Arthropods, including insects, spiders, and crustaceans, have a chitinous exoskeleton that provides support and protection for their bodies.

The reason R is incorrect. Chitinous exoskeletons are waterproof and do not allow for the diffusion of water vapor from the atmosphere to the body. Arthropods have specialized structures, such as spiracles or gills, for gas exchange and obtaining oxygen.
