The correct answer is B. Increase in the demand for raw materials.

Explanation

Railways are a means of transport created in the 16th century, however, their use spread in the 17th and 18th centuries with the Industrial revolution, at that time they were used to transport raw materials from the place of extraction to ports or the cities where the factories were. The railways also meant a change in demand and access to raw materials, because before the use of the railroad they had to be transported in animal-drawn carts such as donkeys, mules or horses that made this task difficult. Therefore, it is possible to affirm that the railroads contributed to the increase in the demand for raw materials because they facilitated their transportation and access to the factory owners. So, the correct answer is B. Increase in the demand for raw materials.
