1. Assertion (A): The emphasis of Jainism on non-violence (ahimsa) prevented agriculturalists from embracing Jainism. 2. Reason (R): Cultivation involved killing of insects and pests.

1. Assertion (A) is true. Jainism's rigorous adherence to non-violence (ahimsa) posed challenges for agriculturalists, as farming practices inevitably involve harming living organisms. 2. Reason (R) is true. Cultivation processes like ploughing, weeding, and pest control result in the killing of insects and pests and other soil organisms, which conflicts with the strict interpretation of ahimsa in Jainism. 3. The inherent violence towards living beings involved in cultivation (R) is the direct reason why the strict emphasis on ahimsa (A) made it difficult for agricultural communities to fully embrace Jainism. Therefore, R is the correct explanation of A.
