D

Explanation: 

Detailed explanation-1: -These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.

Detailed explanation-2: -Most cells are specialised to perform particular functions, such as red blood cells? that carry oxygen around our bodies in the blood, but they are unable to divide. Stem cells provide new cells for the body as it grows, and replace specialised cells that are damaged or lost.

Detailed explanation-3: -Stem cells produce new cells by dividing. In the right conditions, these new cells can then continue to divide and differentiate into specialized cells. Stem cells can also divide to produce new stem cells to replace themselves.

Detailed explanation-4: -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-5: -Tissue-specific stem cells (also referred to as somatic or adult stem cells) are more specialized than embryonic stem cells. Typically, these stem cells can generate different cell types for the specific tissue or organ in which they live.
