Prologed use of seeds of Lathyrus sativus causes a debilitating disorder due to presence of

Options

A. Amygdalin
B. Cyanogenic glucosides
C. Neurotoxin
D. Glucosinolates.

Answer

### Step-by-Step Solution

1. **Identify the Plant**: The question refers to the prolonged use of seeds from *Lathyrus sativus*, commonly known as grass pea.

2. **Understand the Disorder**: Prolonged consumption of these seeds is linked to a debilitating disorder known as Lathyrism.

3. **Identify the Cause**: The key component responsible for Lathyrism is a neurotoxin present in the seeds. This neurotoxin is known as beta-oxalyl amino-L-alanine (BOAA).

4. **Mechanism of Action**: BOAA acts as an excitatory neurotoxin, which means it can overstimulate neurons and lead to mitochondrial toxicity, ultimately causing neurological damage.

5. **Affected Populations**: This disorder primarily affects people in regions such as India, Pakistan, Bangladesh, and Nepal, as well as animals like cattle and horses.

6. **Conclusion**: The debilitating disorder caused by the prolonged use of *Lathyrus sativus* seeds is due to the presence of the neurotoxin beta-oxalyl amino-L-alanine (BOAA).

### Final Answer
The debilitating disorder caused by the prolonged use of seeds of *Lathyrus sativus* is due to the presence of beta-oxalyl amino-L-alanine (BOAA).
