Verified step by step guidance

Understand the role of collagen fibers in the skin: Collagen is a protein that is abundant in the skin, particularly in the dermis layer, and is crucial for maintaining the skin's structure.

Identify the properties of collagen: Collagen fibers are known for their tensile strength, which means they can withstand stretching forces without breaking, providing structural integrity to the skin.

Differentiate between collagen and other skin components: While elastin fibers provide elasticity, allowing the skin to stretch and return to its original shape, collagen primarily provides strength and support.

Consider the options given: Evaluate each option based on the known functions of collagen. Collagen does not regulate body temperature or produce melanin; these functions are related to other skin components.

Conclude with the correct function: Based on the understanding of collagen's properties and roles, the primary function of collagen fibers in the skin is to provide strength and structural support.
