Some animals that live in cold places generally develop a thick coat of hair on their body which helps the animals to trap air in it and keep them warm as air is a poor conductor of heat. Air trapped by the hair on the body of these animals does not let the warmth to escape from the body. Hence, these thick coverings of hair on the animal body protects them from cold.
Therefore the statement cotton and wool are obtained from cotton plant and sheep respectively is true.
Hence, option A is correct.
