  1. Cuticle

  2. Cortex

  3. Medulla

  4. Epidermis

The correct answer is: Cuticle

Liquids can penetrate the hair when swelling raises the cuticle. The cuticle is the outermost layer of the hair shaft and serves as a protective barrier for the inner layers. The cortex, medulla, and epidermis are all part of the inner layers of the hair and are not directly exposed to outside elements. Therefore, they are not directly involved in the penetration of liquids into the hair. The swelling of the cuticle is what allows for the passage of liquids, making A the correct answer.
