The correct option is 1, 2, 3, and 4 because all these Acts have components that influence biodiversity conservation in India. The Import and Export (Control) Act, 1947 regulates the trade of wildlife and their derivatives, thereby protecting certain species from overexploitation. The Mining and Mineral Development (Regulation) Act, 1957 addresses the sustainable extraction of minerals, which can impact habitats and biodiversity. The Customs Act, 1962 plays a crucial role in enforcing wildlife protection laws at borders, thus preventing illegal trade in endangered species. Finally, the Indian Forest Act, 1927 governs forest resources and their management, essential for conserving forest biodiversity. Together, these Acts form a legal framework critical to protecting India’s rich biodiversity.
