Answer

To solve the question regarding the two statements about the Red Data Book and ex-situ conservation, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Analyze Statement I**:
- The first statement claims that the Red Data Book has a record of all animals.
- This statement is incorrect because the Red Data Book, maintained by the International Union for Conservation of Nature (IUCN), specifically lists endangered and threatened species, not all animals.

2. **Analyze Statement II**:
- The second statement asserts that ex-situ conservation is the best method to protect endangered species.
- This statement is generally considered true, especially for species that cannot be effectively conserved in their natural habitats (in-situ). Ex-situ conservation involves taking species out of their natural environments and placing them in controlled settings, such as zoos or botanical gardens, where they can be protected and bred.

3. **Conclusion**:
- Since Statement I is false and Statement II is true, we can conclude that the correct answer is that Statement I is incorrect and Statement II is correct.

4. **Final Answer**:
- Based on the analysis, the answer to the question is that Statement I is false and Statement II is true.
