Answer #1

Centrosomes are the organelles found around nucleus, which contains the centrioles. The centrioles function to provide spindle fibres for the homologous chromosomes and sister chromatids to get separated. Usually, the sister chromatids are two in a cell, so that spindle fibres could be provided from both sides to result in proper cell division. If the cell contains only one centrosome then, chromosomes would not be able to align properly at the metaphase plate, as centrioles will be provided from only one side.

Hence, the correct option is (B).

About the incorrect options-

(A) It happens during prophase not metaphase.

(C) Division would not occur, as there is an error in metaphase.

(D) This event occurs during metaphase and not prophase.
