Which of the following statements about the human respiratory system are INCORRECT ? I. During swallowing , glottis can covered by a thin elastic cartilaginous flap called epiglottis to prevent the entry of food into the larynx. II. The trachea is a straight tube extending up to the mid- thoracic cavity, which divides at the level of the fourth thoracic vertebra into a right and left primary bronchi. III. The trachea , primary secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings made up of hyaline cartilage. IV.

S, T, U, V, W, X, Y and Z are sitting around a circle area, with equal distance amongst each other but not necessarily in the same order. Only two people face the centre and the rest face outside (i.e., in a direction opposite to the centre). Y sits second to left of W. S sits second to left of Y. Only one person sits between S and Z. T sits to immediate right of S. T is not an immediate neighbour of Y. Vis not an immediate neighbour of Y. Both the immediate neighbours of X face the centre. Which of the following is true regarding U as per the given seating arrangement ?
