Final answer:

Charles Darwin's role in the study of Galapagos finches was conducting initial research on finch beaks, leading to his formulation of the theory of evolution.

Explanation:

Charles Darwin played a pivotal role in the study of Galapagos finches and their beaks. The correct answer to the question is A) He conducted the initial research on finch beaks. During his voyage on the HMS Beagle from 1831 to 1836, Darwin observed that the finches on each of the Galapagos islands had uniquely adapted beak shapes and sizes that allowed them to utilize different food sources. These observations contributed to the development of his groundbreaking theory of evolution by natural selection. For example, seed-eating finches had thicker beaks suitable for breaking seeds, whereas insect-eating finches had sharper beaks geared towards stabbing prey. Darwin postulated that the beak of an ancestral species had adapted over time to best equip the finches to acquire food in their specific environments, leading to the variety of species observed on the islands.
