B. More food was grown to feed world populations.

Explanation:

The new imperialism represents the period from the end of the 19th century to the 20th century. European countries primarily "turn" to mass colonization of the African and Asian continents. It is a period of more intensive industrial development. As new economic opportunities open up, new markets are formed, the number of people involved in new imperialist currents increases. Therefore, it was necessary to produce a larger amount of food to meet all the market needs. Advances in science and technology have also led to an increase in population, so food demand has become higher.
