A Correct answer
Explanation

Favism is a hemolytic condition triggered by eating fava beans, occurring in people with Glucose-6-phosphate dehydrogenase (G6PD) deficiency. G6PD is an enzyme crucial for maintaining red blood cell membrane integrity; its deficiency makes RBCs susceptible to oxidative damage from compounds in fava beans. Sickle cell anaemia (B) is a hemoglobin disorder, Alkaptonuria (C) is a metabolic disorder affecting tyrosine metabolism, and Mongolism (D) is an outdated term for Down syndrome (trisomy 21).
