The seeds of the khesari (Lathyrus sativus) plant contain an anti-nutritional neurotoxic factor called cyanoalanine. Khesari is a legume crop grown in certain regions of South Asia and Africa, particularly for its high protein content. However, the presence of cyanoalanine in the seeds makes them potentially toxic if consumed in large quantities or as a major food source over an extended period.

Cyanoalanine is formed when the amino acid L-cysteine reacts with cyanide. This reaction can occur in the seeds of khesari under specific environmental conditions. Consumption of significant amounts of cyanoalanine over time has been associated with a neurological disorder called lathyrism. Lathyrism can lead to irreversible paralysis of the lower limbs and other neurological symptoms.

To mitigate the risk of lathyrism, it is important to limit the consumption of khesari seeds or products derived from them, particularly as a staple food source. Adequate processing techniques, such as soaking, boiling, or roasting, can help reduce the levels of cyanoalanine in khesari seeds, making them safer for consumption in moderation. Hence, the correct answer is option  3.
