Probably c or b to t makes sense
The answer is B: a larger urban population.
One statistic that has functioned steadily as an indicator of the level of industrialization and economic development in countries is the percentage of people living in urban areas, that is to say, people living in cities rather than on rural lands. It is a good indicator because this allows one to infer that the population of such a country is employed not in farming or fishing, but rather in industrial labor, the service industry or forms of human capital exploitation.
St. Petersburg, which is Russia's second largest urban area, was founded in 1703 by the czar Peter the Great. In 1914, the German sounding name was changed to Petrograd. Then, after the death of Vladimir Lenin in 1924, the Soviet Union changed the city's name to Leningrad. Leningrad became St. Petersburg again 67 years later when the Soviet Union collapsed in 1991.<span>
