Vedclass · Answer

(B) The correct answer is $B$. In cockroaches,the tracheal tubes are lined with spiral thickenings of cuticle known as intima,which prevents the tracheal tubes from collapsing. Similarly,the trachea of mammals is supported by $C$-shaped cartilaginous rings,which also ensure that the tracheal walls remain non-collapsible,allowing for continuous airflow during respiration.
