Reproduction, growth, renewal and repair are all reasons for in multicellular organisms.

The correct answer would be cell division.

Explanation:

Reproduction is the process of producing offspring by the asexual or sexual way. It is necessary for cells to divide to produce offspring as parent cells divide to produce offspring (asexual) or produce gametes (sexual). The cell division can be mitosis or meiosis in reproduction based on the mode of reproduction.

Growth of a multicellular organism is also a subject of the cell division so that the cell can join together to form tissue and organs and grow. This process needs mitotic cell division only.

Repair and renewal of an organism also required cell division so it can repair an injured or faulty cell and perform its function.

Thus, the correct answer is cell division.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
