Correct answer: E — Stabilise the segment and defer removal if possible

A large tuberosity fracture that remains attached should be stabilised where possible, with definitive removal deferred to reduce sinus communication and tissue loss. Forceful removal can create a large oroantral defect and compromise future prosthodontic support. The pearl is to stop, reassess, and preserve attached bone when a tuberosity fracture occurs.
