Answer: A COMMUNITY
Explanation:
A biotic community, also known as a biota or ’biocoenosis’, is the group of ORGANISMS of two or more different species that live together and interact with each other within an environment or habitat. Together, the biotic community and the physical landscape or abiotic factors make up an ECOSYSTEM.
A group of organisms constitute POPULATION. But when several populations share a common habitat and its resources, they interact among themselves and develop into a biotic community or simply, a community.

Explanation:
There are four phases which occur during karyokinesis, these are -
- Prophase
- Metaphase
- Anaphase
- Telophase
Telophase is the last phase of karyokinesis. The main events that occur during telophase are-
- Uncoiling of chromosome occurs
- Chromatin is formed
- Spindle breaks down
- Nuclear membrane or nuclear envelope if reformed
Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
