• Option c: Inner follicle is part of the follicle structure, not a muscle.
• Option d: Dermal papilla is a structure in the follicle, not a muscle.

• Option c: Scar is tissue formed after injury, not from clogged ducts.
• Option d: Secretory coil is part of the sweat gland, not related to sebum - clogged pores.
