In Unani medicine, Niqras (Gout) is caused by an accumulation of waste products from the fourth digestion (Hazm Chaharum), making statement (A) correct.
It is commonly known that gout pain affects the finger joints, especially the big toe, which makes statement (C) correct.
However, it does not primarily affect the poor only — diet and lifestyle play bigger roles — so (B) is not strictly correct.
Incidence of gout is more common in males than females, hence statement (D) is incorrect.
Therefore, the correct answer is A and C only.
