The correct answer is Retinol.

Retinol is one of the most active forms of vitamin A and is primarily found in animal-derived foods, such as liver, fish oils, and dairy products. It plays a crucial role in several physiological processes, including maintaining healthy vision, skin health, and proper immune function. In the body, retinol can be converted into other forms of vitamin A, such as retinal and retinoic acid, which are also important for various biological functions. Unlike carotenoids, which are plant-based sources of vitamin A (like beta-carotene), retinol comes directly from animal sources. Adequate intake of vitamin A in its various forms is essential for overall health.
