Option D is correct because the textbook clearly states that the impact of globalisation has not been uniform. While globalisation has benefited well-off consumers in urban areas and producers with skill, education and wealth, many small producers and workers have suffered due to rising competition. Since benefits have not reached all people, not specifically people in developed countries, and certainly not workers in developing countries (who have suffered), none of options A, B, or C accurately describe who has seen improvement in living conditions.
