Final answer:
During the period 1750-1900, Eurasian land-based empires focused on territorial expansion rather than economic integration in response to the rise of global capitalism.
Step-by-step explanation:
The correct answer is D) They focused on territorial expansion rather than economic integration.
During the period of 1750-1900, land-based empires in Eurasia, such as the Russian Empire and Qing Dynasty in China, focused on territorial expansion as a response to the rise of global capitalism. These empires sought to extend their control over new territories and resources rather than integrate their economies into the global capitalist system. This can be seen in the Russian Empire's expansion into Central Asia and the Qing Dynasty's expansion into Tibet and Xinjiang.
