The most accurate response would be:
"The political changes in each of these countries varied, but all of them were impacted in ways that changed the political landscape on a large scale."
This perspective recognizes that while the specifics of industrialization's effects differed among Great Britain, Japan, and Germany—shaping their unique political developments—they all experienced significant transformations that fundamentally altered their political landscapes. In Great Britain, industrialization prompted the rise of a more modern democracy and the expansion of the electorate, while in Japan, it led to the Meiji Restoration and the establishment of a more centralized and imperialistic government. Germany experienced significant political changes as well, culminating in the formation of a united German Empire and shifts towards authoritarianism and nationalism.
