Q. Which one of the following is the correct matching of three items and their grouping category?
A) ilium, ischium, pubis – coxal bones of pelvic girdle
B) actin, myosin, rhodopsin – muscle proteins
C) cytosine, uracil, thiamine – pyrimidines
D) malleus, incus, cochlea – ear ossicles
Explanation
[Solution from source] Each coxal (hip) bone of the pelvic girdle is formed by fusion of the ilium, ischium and pubis. Rhodopsin is a visual pigment, thiamine is a vitamin (thymine is the pyrimidine) and the cochlea is part of the inner ear, not an ossicle. Answer (1).
