Final answer:
A cicatrix is a scar that forms when there is repair of skin damage but the skin fails to regenerate the original skin structure. It is collagen-rich and does not allow for the regeneration of accessory structures like hair follicles and sweat glands. Hence the correct answer is option A
Step-by-step explanation:
A cicatrix is a scar. Scarring occurs when there is repair of skin damage but the skin fails to regenerate the original skin structure. Fibroblasts generate scar tissue in the form of collagen, resulting in a collagen-rich skin that differs from normal skin. Scars do not allow for the regeneration of accessory structures like hair follicles, sweat glands, or sebaceous glands.
Hence the correct answer is option A
