Live specimens of organisms are found in which of the following

The correct answer is botanical gardens and zoological parks (zoos).

Let us understand why this is the correct option by examining the purpose and nature of each scientific repository listed in the options:
1. Botanical Gardens: These are specialized gardens that maintain collections of living plants for reference, education, and scientific research. Each plant is labeled with its botanical/scientific name and its family. Since the plants are kept alive and growing, they contain live specimens.
2. Zoological Parks (Zoos): These are enclosed areas where wild animals are kept in protected environments under human care. This allows us to learn about their food habits and behavior. Since the animals are kept alive, they represent live specimens.
3. Museums: Museums generally have collections of preserved plant and animal specimens for study and reference. Specimens are preserved in containers or jars in preservative solutions, or dried. Insects are preserved in insect boxes after collecting, killing, and pinning. Larger animals like birds and mammals are usually stuffed and preserved. Therefore, museums contain dead, preserved specimens, not live ones.
4. Herbaria: A herbarium is a storehouse of collected plant specimens that are dried, pressed, and preserved on paper sheets. These sheets are arranged according to a universally accepted system of classification. Since the plant specimens are dried and pressed, they are dead specimens rather than live ones.

Therefore, live specimens of organisms are found specifically in botanical gardens and zoological parks (zoos).
