Best answer

Answer: 2. Kinetochore of the chromosome

Key idea: Spindle fibres attach to the kinetochore.

The kinetochore is a disc-shaped protein structure on the centromere of each chromatid. The centromere is the primary constriction; the kinetochore sits on it and holds the microtubules. Telomeres are chromosome ends.
