I think sister groups. Imagine them having the same parents.
The correct answer is differentiation.
Planetary differentiation can be defined as a process in which separation of different constituents of the planetary body takes place.They are separated based on their physical or chemical behavior, where the body divides into different layers: the less denser materials rise up to the surface and the more denser substance of the planet sinks.
Example: dwarf planets.

The question is incomplete as it does not have the options which are:
A) eight legs.
B) two pairs of antennae.
C) a sessile lifestyle.
D) an open circulatory system.
E) parapodia.
Answer:
D) an open circulatory system.
Explanation:
In the given question, the characteristics of an organism are given which are:
1. Exoskeleton- outer covering composed of cuticle
2. system of tubes for gas exchange- do not respire but has tubes called trachea from which the air diffuses
3. modified segmentation- segmented bodies
All these characteristics show that the organism belongs to the Arthropods group of animals.
The Arthropods since having trachea for the diffusion of gas, therefore, possess an open circulatory system in which blood does not flow in the vessels but the open cavities in the body.
Thus, Option-D is the correct answer.
