• A. Stratum Germinativum
• B. Stratum Spinosum
• C. Circulatory System
• D. Hair Follicle

Answer: (B)

The spiny layer is the Stratum Spinosum, located just above the basal layer. Its name comes from the spiky appearance of keratinocytes in histology, caused by many desmosomes that hold the cells together. These intercellular connections give the epidermis its strength and flexibility as cells move upward from the basal layer. Langerhans cells reside here as part of the skin’s immune defense. The basal layer lies beneath and is where cells divide, while options like a circulatory system or a hair follicle are not epidermal layers, so they don’t fit.
