The correct option is A Prothorax
A.Prothorax – It is the
foremost of the three segments in the thorax of an insect, and bears the first
pair of legs and wings(elytra).
B.Mesothorax - is the middle of the three
segments in the thorax of an insect, and bears the second pair of legs. Its
principal sclerites (exoskeletal plates) are the mesonotum (dorsal), the
mesosternum (ventral), and the mesopleuron (lateral) on each side. All
adult insects possess legs on the mesothorax.
C.Metathorax – is the posterior of the three
segments in the thorax of an insect, and bears the third pair of legs. Its
principal sclerites (exoskeletal plates) are the metanotum (dorsal), the
metasternum (ventral), and the metapleuron (lateral) on each side.
D.Abdomen – lower part of the body.
So,
the correct option is ‘Prothorax’.
