B. Metathoracic
C. Mesothoracic
D. Both 2 and 3

Answer 1

Periplaneta americana is the scientific name of cockroach. The body of a cockroach is three-segmented, including the Head, Thorax, and Abdomen. Head incorporates compound eyes and a pair of antennae that help them to get odor and tremors. Thorax incorporates 3 sets of legs (6 legs total) and 2 sets of wings.

Complete answer:
A cockroach thorax is a connection for 3 sets of legs and 2 sets of wings. The name of all the 3 sets of legs is according to the region to which they join. The legs which are nearest to the cockroach head are known as prothoracic legs. These are the cockroach's smallest legs, and they act as brakes when the bug runs. A segment of the prothorax additionally covers the cockroach head. Mesothoracic legs are the center legs. They move to and fro to either speed the cockroach up or back it off. The pair of wings emerge from the mesothorax and are known as the tegmina.
Metathoracic legs are very long. They are the cockroach back legs, and they push the cockroach ahead. Utilizing its Metathoracic legs, a bug can move around 50 body lengths in a second. The sets of wings that originate from the metathorax are known as the hindwings. The two sets of wings emerge from both metathorax and mesothorax.

So, the right answer is option D.

Note:
There is a tough exoskeleton i.e. brown and made of chitin. The solidified plates of the exoskeleton are known as the sclerites. The tegmen is dark and encloses the hind wings, which are membranous, transparent, and utilized in flight. There are cockroaches found over the globe, to the tune of more than 4,500 species.
