Which structure in this cell has a similar function to that of skin cells that interact to form a protective barrier in animals?

The correct answer is B) Cell membrane.

The cell membrane acts as a protective barrier, similar to skin cells in animals. It regulates what enters and exits the cell while also providing structural support and protection. Just as skin cells form a physical barrier to protect underlying tissues, the cell membrane serves a similar function at the cellular level.
