Solution
The correct option is D Centrosome
During mitosis, the duplicated chromosomes are positioned at the middle of the cytoplasm. They are segregated so that the daughter cells can get a copy of the original DNA. This is made possible by the presence of microtubules (spindle fibres), which pull the chromosomes into each of the cells. These fibres arise from the centrioles, which are on either side of the cells, and may have even smaller microtubules referred to as aster. These are thought to serve as braces for the functioning of the fibres. So, the correct answer is option D.
