Final answer:
Jamaica qualifies to be a member of the Commonwealth of Nations as it is an independent country.
Step-by-step explanation:
Jamaica is a member of the Commonwealth of Nations because it meets the criterion of being an independent country (option D). Membership in the Commonwealth is not determined by the official language (option A) or being a former colony (option B). While Jamaica being a large island in the Caribbean (option C) may be relevant to its geography, it is not a qualifying criterion for Commonwealth membership.
