Verified step by step guidance

Step 1: Understand the structure of the epidermis, which consists of multiple layers, including the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum (in thick skin), and stratum corneum.

Step 2: Focus on the stratum granulosum, which is the middle layer of the epidermis. This layer is crucial for the process of keratinization, where keratinocytes begin to produce keratohyalin and lamellar bodies.

Step 3: Learn about keratinization, a process where keratinocytes accumulate keratin and undergo structural changes to form a protective barrier. This process is essential for skin's waterproofing and protection.

Step 4: Differentiate keratinization from other processes mentioned in the options, such as phagocytosis (cell engulfing particles), melanogenesis (production of melanin), and mitosis (cell division). None of these processes occur in the stratum granulosum.

Step 5: Recognize that keratinization is the correct answer because it is the primary process occurring in the stratum granulosum, contributing to the formation of the skin's outer protective layer.
