Red list contains data or information on:

Options

A. Threatened species
B. Marine vertebrates only
C. All economically important plants
D. Plants whose produce are in international trade

Answer

To answer the question regarding what the Red List contains data or information on, we can follow these steps:

### Step 1: Understand the Red List
The Red List is a comprehensive inventory of the global conservation status of biological species. It is maintained by the International Union for Conservation of Nature (IUCN) and serves as a critical tool for assessing the risk of extinction faced by various species.

### Step 2: Identify the Purpose of the Red List
The primary purpose of the Red List is to highlight species that are at risk of extinction. This includes categorizing species based on their population status, threats, and conservation needs.

### Step 3: Analyze the Options Provided
1. **310 species**: This option refers to a specific number of species that are at risk. The Red List does indeed contain data on species that are endangered or threatened.
2. **Marine Vertebrates only**: This option is too narrow, as the Red List covers all types of species, not just marine vertebrates.
3. **All economically important plants**: This is also incorrect because the Red List does not specifically focus on economically important plants alone.
4. **Plants whose produce are in international trade**: Similar to the previous option, this is too specific and does not encompass the full scope of the Red List.

### Step 4: Conclusion
Based on the analysis, the correct answer is that the Red List contains data or information on species that are at risk of extinction, which can be represented by the option referring to "310 species."

### Final Answer
The Red List contains data or information on endangered species, specifically those that are at risk of extinction.
