Explanation

Mitosis occurs in all somatic (body) cells for growth, repair, and maintenance. Skin cells (epidermis), heart cells (cardiac muscle), and kidney cells all undergo mitosis to replace damaged or dead cells. While heart muscle cells divide slowly, they still divide. 'All of these' is correct because mitosis is universal in somatic tissues.
