Japans industrialization was greatly helped bya.large mineral deposits in hokkaido b. a growing support for democracy c.a centralize pro-buisness...

Of these, I would say that the best answer is C -- a
centralized government that was friendly to business.

This
centralized government was the government of the Meiji Emperor.  This government held
all power in Japan after the civil wars had ended.  It was very concerned with making
sure that Japan could become a modern country.  Because it was concerned with
modernizing, it helped businesses so that Japan could have an industrial economy that
would allow it to be as strong as the European countries
were.

There were some mineral deposits on Hokkaido, but I
do not believe they were as important as the support of the Meiji
government.
