The correct answer to this question is option 2: nerves.

Nerves are a type of tissue in the human body where no cell division occurs after birth. Nerves are responsible for transmitting signals and information throughout the body. They are made up of specialized cells called neurons, which have distinct structures that allow them to send and receive electrical impulses.

Unlike some other tissues in the body, such as the skin or gastrointestinal tract, nerves do not undergo continuous cell division or regeneration. Once the nerves are formed during embryonic development, the number of nerve cells remains relatively stable throughout a person`s life. Therefore, if any damage occurs to the nerves, such as due to injury or disease, it often results in permanent loss of function.

It is important to note that while nerves themselves do not undergo cell division after birth, there are other types of tissues in the body that do have ongoing cell division, such as the skin, hair follicles, and blood cells.
