With reference to the above passage, which of the following would assist us in coping with the climate change?
1. Conservation of natural water sources
2. Conservation of wider gene pool
3. Existing crop management practices
4. Migration corridors

Select the correct answer using the code given below.

Correct Option: 1, 2 and 4 only

Based on the passage, coping with climate change requires a diverse set of natural assets. Conserving natural water sources (1) is vital for maintaining agricultural productivity. Conserving a wider gene pool (2) of crops and wild relatives ensures genetic diversity, enabling crops to adapt to changing temperatures and pests. Establishing and protecting migration corridors (4) is essential to allow species and biodiversity to relocate as ecosystems shift due to global warming. However, relying on existing crop management practices (3) is counterproductive because climate change renders historical practices obsolete, requiring us to reform rather than preserve existing methods. Thus, 1, 2, and 4 assist us, while 3 does not. Hence, option B is correct.
