Explanation:

- Privatisation: This involves transferring ownership of a business, enterprise, or public service from the government to private entities. It does not directly relate to global market integration.

- Liberalisation: This entails relaxing government restrictions, often in areas like trade, to encourage more competition and efficiency. It can be a step towards globalisation but is not synonymous with creating a single global market.

- Globalisation: This is indeed the integration of world economies into a single market. It involves the removal of trade barriers, leading to increased interconnectedness and interdependence among countries.

- Both (a) and (b): This option suggests a combination of privatisation and liberalisation, but neither directly results in the integration of global economies as a single market in the sense that globalisation does.
