In Unani medicine, specific organs and structures are classified based on their role and nature.
Ribat refers to ligaments and connective tissues which provide coolness and support — hence, linked to Uzw Barid (III).
Dimagh means the brain, which is a chief organ that governs major functions — so it matches with Uzw Raees (I).
Khusiyah are the testes, which are simple reproductive organs — these relate to Uzw Mufrad (II).
Aasab refers to the nerves which control movements and reproductive strength — hence, matched with Quwwat Muwallida (IV).
Therefore, the correct matching is: (A)-(III), (B)-(I), (C)-(II), (D)-(IV).
