The correct spelling is 'Hospitable' (option D) - meaning friendly and welcoming to guests or strangers. The root word is 'hospital' but with the suffix '-able'. Option A (Hospiteble) has an incorrect 'e' before 'ble'. Option B (Hospittable) incorrectly doubles 't'. Option C (Hospitabel) incorrectly uses 'bel' instead of 'ble'. Only option D follows correct English spelling rules.
