Solution
The correct option is C Tracheae
The basic
insect respiratory system consists of a series of rigid tubes, called tracheae (singular
trachea), connected to the outside via pairs of pores
called spiracles (typically one pair per segment on the sides of the
thorax and abdomen, lacking on certain segments). Air enters the system via
the spiracles and the tracheae are air-filled. The spiracles can often be
opened and closed and lead into short tracheae that enter a pair of
longitudinal tracheal trunks, which are the main tracheal
tubes. Silkworm is also belongs to the class insect. So, the
correct answer is ‘Tracheae’.
