Spindle fibres attach on to
A
kinetochore of the chromosome.
B
centromere of the chromosome.
C
kinetosome of the chromosome.
D
telomere of the chromosome.

Spindle fibres attach at kinetochores.
Detailed Solution
During metaphase of mitosis, spindle fibres arising from the centrioles attach to the kinetochores of the chromosomes. During anaphase they contract to pull the chromosomes towards the poles.
