Answer: The correct answer is-
(2) mitosis of body cells.
Mitosis is a type of cell division in which a parent cell produces two daughter cells having same number of chromosomes as that of their parent cell.
It occurs through a series of 5 stages that are- Prophase, metaphase, anaphase, telophase, and cytokinesis.
It is responsible for the growth of organisms and the repair of damaged tissues (in case of multicellular organisms) as new, identical cells (that are identical to each other) are produced from the parent cell.
Thus, option 2) is the right answer.
