Answer: iii. undertook political reform and economic expansion
Step-by-step explanation:
During the Meiji Restoration, Japan took back power from the Shoguns and gave it back to the Emperor. This period saw the rise of industrialization, education and generally economic policies that aimed to bring Japan up to speed with the Western nations.
This was similar to Japan after WWII.

This led to much advancement in the economic of the nation such that after some decades it became a first world country.
