• A. Kinetochore
• B. Kinetosome
• C. Satellite body
• D. Chromonema

Answer 1

The correct option is A Kinetochore

The most diagnostic character of the centromere is the kinetochore. The kinetochore is the protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart. The kinetochore forms in eukaryotes assemble on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.

So, the correct answer is option A.
