The correct answer is C. Guilds likely became less powerful as artisans were replaced by machinery. During the Industrial revolution mass production allowed businesses to produce larger quantities using less capital. They needed less workers when they began incorporating machines that could not only produce more products quicker, but could also produce them uniformly. This meant that fewer artisans would have been needed to make certain products.
