Correct answer: E — Full-thickness (mucoperiosteal) flap

A full-thickness (mucoperiosteal) flap elevates the mucosa and periosteum together as a single layer, exposing the underlying alveolar bone. It is the standard flap for surgical extractions, apicoectomies, cyst enucleation, and implant placement. A split-thickness flap (mucosa only, leaving periosteum on bone) is used in specific periodontal procedures where bone exposure is undesirable (e.g., certain graft procedures).
