Step 1 : Understanding the Question
This question requires an understanding of biodiversity conservation strategies, specifically distinguishing between {in situ} (on-site) and {ex situ} (off-site) methods.
Step 2 : Key Formulas and approach
The categorization depends on the location of protection.
1. {In situ} = Within the natural habitat.
2. {Ex situ} = Outside the natural habitat.
The approach is to evaluate each facility's function.
Step 3 : Detailed Explanation
Sacred Groves (A): These are undisturbed forest patches protected by local communities due to cultural or religious beliefs. Since the species are preserved in their (A) natural habitat, it is an {in situ} method.
Botanical Gardens (C): These are man-made facilities where plants are brought from various places to be grown. Because it is (B) away from their home, it is {ex situ}.
Wildlife Safari Parks (B): These are managed enclosures where animals are kept for tourism and protection. This is (C) off-site management, making it {ex situ}.
Seed Banks (D): These are high-tech facilities used to store genetic material (seeds) under controlled conditions. This is a purely (D) artificial {ex situ} method.
Step 4 : Final Answer
Among the options, Sacred Groves is the only {in situ} method. Thus, the correct choice is (A).
