Hint: Cell divides and reproduces in two ways, one is meiosis and another one is mitosis. Meiosis results in four sex cells while the mitosis gives two daughter cells which are identical to each other. And the daughter cells have the same number of chromosomes as present in the parent cell.

Complete answer:
In dividing animal cells, the spindle contains asters at the two poles. Such a type of spindle is called a centric or amphiaster. In-plant cells, spindle apparatus formed is acentric(without centriole) and anastral (without spindle apparatus). It is typically seen in higher plants. The aggregation, arrangement and bonding together of a set of components for the formation of spindle fibre, in the absence of centrosomes, duplicated chromosomes are drifted apart by the array of microtubules and the associated molecules. Mitosis generally occurs in four types of phases. The phases are as follows: prophase, metaphase, anaphase and telophase. Mitosis is also defined as the equal distribution of the chromosomes to form the identical daughter cells. It maintains the constant number of chromosomes throughout the process in all body cells of the organism.
Hence, the correct answer is option (C).

Note: Mitosis is the term given by ‘Walther Flemming’ in 1882. He observed that the chromosomes equally distribute themselves from splitting longitudinally into two daughter cells during the cell division. The final result of mitosis is the growth of the eukaryotic organism and replacement of some eukaryotic cells.
