D. plants whose products are in international trade

Answer

**Step-by-Step Solution:**

1. **Understanding the IUCN Red List**: The IUCN Red List, established by the International Union for the Conservation of Nature (IUCN), is a comprehensive inventory that assesses the conservation status of various biological species globally.

2. **Definition of Threatened Species**: The term "threatened species" refers to species that are at risk of extinction. This includes species with declining populations or those that are facing significant threats to their survival.

3. **Scope of the Red List**: The Red List includes data on all threatened species, which encompasses both plants and animals. It is not limited to specific categories such as marine vertebrates or economically important plants.

4. **Evaluating the Options**:
- **Marine Vertebrates Only**: This option is incorrect because the Red List covers all threatened species, not just marine vertebrates.
- **All Economically Important Plants**: This option is also incorrect as the Red List does not focus solely on economically important plants.
- **Plants Whose Products are in International Trade**: This is incorrect as well; the Red List does not specifically list plants based on their trade status.

5. **Conclusion**: The correct answer is that the IUCN Red List contains data or information on threatened species, which includes a wide range of plants and animals at risk of extinction.

**Final Answer**: The IUCN Red List contains data or information on threatened species.
