The most accurate response is:
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.
Industrialization had significant effects on the political structures and ideologies in Great Britain, Japan, and Germany. In Great Britain, the rise of the working class and the demand for reforms led to the expansion of suffrage and the development of labor rights. In Japan, the Meiji Restoration initiated a transformation that modernized the political system and adopted Western practices. In Germany, industrialization fueled nationalism and contributed to the unification of the German states under a strong central government. In each case, industrialization was a catalyst for substantial political change.
