To solve this problem, we need to identify which option correctly matches the conservation methods with their examples. Let's analyze each option:$\newline \bullet$Option 1:$\newline$ - In situ conservation: National Park.$\newline$ - In situ conservation involves protecting species in their natural habitats. National Parks are designated areas where wildlife is protected in its natural environment.$\newline$ - Ex situ conservation: Botanical Garden.$\newline$ - Ex situ conservation involves protecting species by removing part of the population from a threatened habitat and placing it in a new location. Botanical Gardens are places where plants are grown for conservation, research, and education.$\newline$ - Both pairs are correct.$\newline \bullet$Option 2:$\newline$ - In situ conservation: Cryopreservation.$\newline$ - Cryopreservation is an ex situ conservation method where cells, tissues, or seeds are preserved at very low temperatures.$\newline$ - Ex situ conservation: Wildlife Sanctuary.$\newline$ - Wildlife Sanctuaries are areas where animals are protected in their natural habitats, which is an in situ conservation method.$\newline$ - Both pairs are incorrect.$\newline \bullet$Option 3:$\newline$ - In situ conservation: Seed Bank.$\newline$ - Seed Banks store seeds outside their natural habitat, which is an ex situ conservation method.$\newline$ - Ex situ conservation: National Park.$\newline$ - National Parks are areas where wildlife is protected in its natural environment, which is an in situ conservation method.$\newline$ - Both pairs are incorrect.$\newline \bullet$Option 4:$\newline$ - In situ conservation: Tissue culture.$\newline$ - Tissue culture is an ex situ conservation method where plant cells are grown in a controlled environment.$\newline$ - Ex situ conservation: Sacred groves.$\newline$ - Sacred groves are areas of forest preserved by local communities, which is an in situ conservation method.$\newline$ - Both pairs are incorrect.$\newline$Therefore, the correct option is Option 1, where both pairs have the correct combination.
