A
It can become a plant stem.
B
It can reproduce by itself.
C
It can become any type of animal cell.
D
It can become any type of plant cell.
Explanation: 

Detailed explanation-1: -Stem cells are different from other cells in the body in three ways: They can divide and renew themselves over a long time. They are unspecialized, so they cannot do specific functions in the body. They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells.

Detailed explanation-2: -Stem cells are of great benefit to cell-based gene therapy because they are self-renewing and thus might reduce or eliminate the necessity for repeated administrations of the therapeutic cells. The overall goal of gene therapy is to cure diseases caused by malfunctioning genes.

Detailed explanation-3: -Plant stem cells do not undergo the process of ageing and senescence, they undergo differentiation to form specialized and unspecialized cells. These in turn have the potential to develop into any organ or tissue. Therefore, plant stem cells are termed as totipotent cells.

Detailed explanation-4: -Furthermore, whereas animal stem cells are in general responsible for maintaining a specific tissue, plant stem cells generate complete organs, and as such resemble animal pluripotent embryonic stem (ES) cells.
