Small disc-shaped structures at the surface of the centromeres are called kinetochores. These structures serve as the sites of attachment of spindle fibres to the chromosomes.

In prophase :–
1 Centrioles duplicate
2 Chromosomes are seen to be composed of two chromatids attached together at the centrosome
3 The chromosomal material becomes untangled during the process of chromatin condensation
4 All are correct
Explanation:
During prophase, chromosomal material condenses to form compact mitotic chromosomes. Chromosomes are seen to be composed of two chromatids attached together at the centromere. Centrosome which had undergone duplication during interphase, begins to move towards opposite poles of the cell in this phase.

Statement A : Centrosome undergones duplication during M-phase Statement B : Centrosome begins to move towards opposite poles of the cell during inter phase.
1 Statement-A is correct but Statement-B is incorrect.
2 Statement-A is incorrect but Statement-B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Centrosome which had undergone duplication during S-phase of interphase, begins to move towards opposite poles of the cell during prophase.

In the given diagram A and B represents_
1 A - Early Prophase B - Metaphase
2 A - Early Prophase B - Late Prophase
3 A - Early Anaphase B - Late Anaphase
4 A - Anaphase B - Metaphase
Explanation:
Figure A represents Early Prophase where nuclear membrane is still intact and chromatin is yet to condense. Figure B represents Late Prophase where nuclear membrane is disintegrated and chromatin is condensed to chromosome.
