- B. Gene libraries
- C. Herbariums
- D. Gene pools
Explanation
The viable material of an endangered species can be preserved by gene banks. A gene bank is an institute that maintains stocks of viable seeds (seed banks), live growing plants (orchards), tissue cultures and frozen germplasm with a whole range of genetic variability. Gene banks are often used in conjunction with other conservation strategies to ensure the resilience and persistence of endangered species.
