The correct answer is - option B. sister chromatids.
Explanation:
When a one strand DNA of a chromosome replicates itself into two identical copies of DNA formed, these two identical DNA copies are called as sister chromatids.
Dyad is a pair of sister chromosomes and each sister chromosome have two chromatids. The formation of the sister chromatids takes place in the S phase of interphase which is also called the synthesis phase.

Explanation:
Homeostasis is a self-regulating technique by which systems
in the body maintain stability and tend to adjust to optimal conditions which
are essential for survival. Thereby, the role of homeostasis is to help the
body maintain constant internal environment. A good example of homeostasis
would be ‘drinking excess alcohol causes vomiting’.
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
