Answer:
c) improve the quality of customer service
Step-by-step explanation:
this is because public sector organisations are not fond of making profits, though it's highly desirable. they are owned and controlled by the government and aim to provide service to the public and for the good of other people, the organisations are usually funded by taxes and aren't really profitable as they generally exist to provide goods and services to public using public funds so improving customer service is likely to be an objective compared to the other options as they serve a purpose of satisfying public needs and not making profits
