Solution

The correct option is A Stratum corneum
Stratum corneum is the only layer of skin we see with our eyes. It is made up of dead skin cells filled with a tough protein called keratin. It serves as a hard protective layer against environmental trauma, such as abrasions, light, heat, chemicals, and microorganisms.
