Answer:
Connect the centromere to microtubules. (Option A)
Step-by-step explanation:
The kinetochore is known as the complex of protein which is disc shape in structure. The structure of kinetochore is divided into three parts: inner region, outer region, and fibrous corona. Each part of the kinetochore works in its own way in the separation of the sister chromatids.
During the process of cell division (mitosis, and meiosis) kinetochore collects on the centromere and allows the chromosome to link with microtubules.
