• B. Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the structure of the epidermis, which is the outermost layer of the skin. It consists of multiple layers of cells that serve as a protective barrier.
2. Step 2: Recall the correct order of the layers of the epidermis from superficial (outermost) to deep (innermost). The layers are: Stratum corneum, Stratum lucidum (only present in thick skin like palms and soles), Stratum granulosum, Stratum spinosum, and Stratum basale.
3. Step 3: Analyze the options provided in the question and compare them to the correct order of the layers. Look for the sequence that matches the correct order.
4. Step 4: Pay attention to the presence of the Stratum lucidum, which is only found in thick skin. If the question specifies thick skin, ensure this layer is included in the sequence.
5. Step 5: Select the option that correctly lists the layers in the order: Stratum corneum, Stratum lucidum, Stratum granulosum, Stratum spinosum, Stratum basale.
