Final answer:
The correct answer is C) Reduction in chromosome number. Mitosis is a process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
Step-by-step explanation:
The correct answer is C) Reduction in chromosome number. Mitosis is a process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. During mitosis, the chromosomes duplicate (A) and then separate into two sets (D), which are then enclosed by a cell membrane in the process of cytokinesis (B). However, there is no reduction in chromosome number (C) during mitosis, as the daughter cells retain the same number of chromosomes as the parent cell.
