What process does a multi-cellular organism use to replace its damaged body cells?
A
mitosis
B
meiosis
C
replication
D
transcription
Explanation: 

Detailed explanation-1: -In all complex multicellular organisms (eukaryotes), cell duplication occurs by a process called “mitosis” or cell division.

Detailed explanation-2: -The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-3: -Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.

Detailed explanation-4: -Answer and Explanation: Division to replace damaged or worn-out cells are called cell division, in particular, MITOSIS.

Detailed explanation-5: -Multicellular organisms depend on mitosis for growth and repair. When an animal, plant or other multicellular organism grows, it makes more cells through mitosis. Organisms can repair some of their tissues, using mitosis to regenerate new cells.
