The right answer is A.

Explanation:

In modern history, the Industrial Revolution is a process of change from an economy largely based on agriculture and the production of handicrafts, to an economy based on industry and machine manufacturing. Britain was the country where this process started in the 18th century and from there it spread to Europe and other parts of the world.

It is characterized by significant technological advances such as the use of new raw materials, mainly iron and steel; the use of new energy sources - fuels, coal, the steam engine, electricity, and the internal-combustion engine-; new machines were designed and installed that allowed a smaller expenditure of human energy ; there were also outstanding developments in transportation and communication such as the steam locomotive, steamships, telegraph, etc.

Another major socioeconomic impact of the application of new technologies was a new division of labor, specialization and production: the factory system. Massive use of resources and mass production became possible.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
