Solution

The correct option is C Neurotoxin
Lathyrism is a disease caused by eating seeds of species of Lathyrus (the grass pea), mainly L. sativus (the chickpea or khesari), L. cicera (flat-podded vetch) and L. clymenum (Spanish vetchling). It affects mostly people in Bangladesh, India, Pakistan, Nepal and Algeria but is sometimes found in France, Italy, Spain and Australia. This disease affects horses and cattle as well as in man.
Beta-Oxalyl-amino-L-alanine acid (BOAA), an excitatory neurotoxin and glutamate agonist, has been identified as the constituent of the chick pea responsible for the disease. BOAA appears to exert its effects through mitochondrial toxicity.
Prolonged use of seeds of Lathyrus sativus causes a debilitating disorder is not due to presence of glucodsinolates, amygdalin and cyanogenic glucosides.
Therefore, the correct answer is option C.
