(A) Wings
(B) Three pairs of legs
(C) Jointed appendages
(D) Antenna

Answer 1

Hint: Both honey bee and cockroach belong to the phylum Arthropoda. It comes from the Greek word arthro meaning joint and pous meaning foot. Their cuticle is made up of chitin and they possess joint limbs.

Complete answer:
Let’s discuss the choices and find the correct answer.
- Wings are defined as a kind of fin from where lifts are formed. Wings possess some cross-sections that are streamlined and they perform as airfoils. The efficiency of the aerial dynamic of wings is called lift to drag ratio.
- The body parts of arthropods are composed of mainly three segments that include antennae, some pairs of legs, and two wings. The parts of their body are known as the head, thorax, and abdomen.
- The body part from where the growth of the body of an organism begins having a joint in the body. These are the main features of the phylum Arthropoda. It includes wings, legs, and other mouthparts.
- The heads of arthropods remain connected by one or two segments. These are called antennas. In several organisms, they vary rapidly and are composed mainly of more than one joint segment.

Hence Option (C) Jointed appendages is the correct answer.

Note: Arthropods are regarded as the most species rich phylum in the environment. It consists of about $80\%$ of the data of all the species present here thus millions of species are reported in this phylum.
