Evolution, specifically mutation.
Remember Darwin's birds on the Galapagos. Well, those birds are examples of new species coming from an old one.
See, once a group of birds left Ecuador and landed on one of the islands. In order to survive, they mutated to fit the island's lifestyle.
Later, birds from that island migrated to the others, and repeated the process. Soon, there will multiple species of finches, living together. All because of one finch.
So look for mutation or migration in your answer
The semicircular canals are part of the bony labyrinth found in the inner ear. It is known for establishing and detecting equilibrium through sensory cells. This is transmitted to the endolymph by pressure using motion. On the other hand, the cochlea which is also a part of the bony labyrinth detects sound.

Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.
