Read the given passage having some variables and few italicised words. Different respiratory organs are present in different organisms. X is the main respiratory organ in humans. Respiratory system of cockroach consists of small openings on the sides of its body called tracheoles which are connected to the tubes called tracheae that are further branched into spiracles. Scoliodon respires through Y which is richly supplied with blood vessels. Z is the main site of gaseous exchange in plants. Each Z is guarded by two kidney shaped subsidiary cells which are further flanked by specialised epidermal cells called guard cells.
Select the correct option regarding the words italicised in the given passage.

AThe positions of spiracles and tracheoles should be interchanged.
BThe position of tracheoles and tracheae should be interchanged.
CSubsidiary should not be replaced as it is correctly mentioned.
