The correct answer is option 2: intellectual property protection. The TRIPS Agreement, which stands for Trade-Related Aspects of Intellectual Property Rights, is an international agreement that sets standards for the protection and enforcement of intellectual property rights. Intellectual property refers to creations of the mind, such as inventions, literary and artistic works, trademarks, and designs, that are protected by laws.

Option 1: international tariff regime is incorrect. Tariffs are taxes or fees imposed on imported goods and services, and they are not directly related to the TRIPS Agreement.

Option 3: international practices on trade facilitation is incorrect. While the TRIPS Agreement does touch upon various aspects of international trade, it specifically focuses on intellectual property protection, not trade facilitation measures.

Option 4: international taxation of property is incorrect. The TRIPS Agreement does not deal with taxation matters; its primary focus is on intellectual property rights.

In summary, the TRIPS Agreement addresses and sets standards for the protection of intellectual property rights, making option 2 the correct answer.
