Correct Option (A)
Statement 1 is correct. The passage indicates that natural pest control using botanical pesticides is safer for the user and the environment. It explicitly states that these compounds break down into harmless substances within hours or days, and they contribute to the reduction of human health hazards.
Incorrect Options:
- Statement 2 is incorrect. The passage clearly states that synthetic pesticides are generally persistent in the environment, whereas botanical pesticides are biodegradable and decompose easily and quickly. Therefore, botanical pesticides are not persistent.
- Statement 3 is incorrect. While the passage mentions that botanical pesticides help in the maintenance of biological diversity of predators, it does not claim that they are essential for maintaining the biodiversity of any ecosystem. Their role is described as supportive rather than indispensable for overall ecosystem biodiversity.
