What pain reliever is made from the gallbladders of cattle?

The choice of "None of the above" is correct because none of the listed options (Ibuprofen, Cholagogues, or Cholecystokinin) are pain relievers derived from cattle gallbladders.

Ibuprofen is a widely used nonsteroidal anti-inflammatory drug (NSAID) that is synthesized chemically and not derived from animal sources. Cholagogues refer to substances that stimulate the bile flow from the gallbladder, and while they involve bile secretion, they are not pain relievers themselves. Cholecystokinin is a hormone that is released by the small intestine, promoting digestion and bile flow, but it is not a pain medication.

In summary, the correct answer acknowledges that none of the choices offered are related to a pain reliever sourced from cattle gallbladders.
