Answer:

d improved genetic modification of food allowed for increased harvests in LDCs.

Explanation:

During the second agricultural revolution which lasted between the 17th and early 18th century, the industrial revolution was also occurring during this period.

This led to an improvement in the level of agricultural production which includes new crop rotation methods, selective breeding of domestic animals, and generally genetic modification of food in less developed areas or countries.

Hence, in this case, the correct answer is option D "improved genetic modification of food allowed for increased harvests in LDCs."
