The Correct Option is B
Solution and Explanation
Step 1: Collagen is the most abundant protein in mammals and the main component of connective tissue, built from amino acids wound into triple-helical fibrils.
Step 2: Of the many described collagen types, the five most common have specific tissue distributions. Type I is found in skin, tendon, vasculature, organs, and bone.
Step 3: The distractors map elsewhere: Type II is the main collagen of cartilage, Type III forms reticular fibres, and Type IV forms the basal lamina of basement membranes.
Step 4: Since skin is dominated by Type I collagen, the correct answer is Type I.
