Solution

The correct option is A Centromere
The centromere is the part of a chromosome that links sister chromatids. During cell division, spindle fibres attach to the centromere via the kinetochore. Centromeres were first defined as genetic loci that direct the behaviour of chromosomes.
So, the correct answer is option B.
