The correct answer is **a) brain and muscle cells**.
Most mature brain cells (neurons) and many muscle cells (especially skeletal muscle fibers) do not perform mitosis and are considered post-mitotic, meaning they do not divide. In contrast, skin and hair cells (b), sperm and egg cells (c), and many blood and organ cells (d) are capable of undergoing mitosis or have regenerative processes.
