Answer:
a. south korea has more private business than india and china
Explanation:
South Korea is an advanced, market-oriented economy, with a GDP Per capita of over 30,000 dollars, much higher than India's or China's.
Even if the South Korea economy has very strong conglomerates like Samsung and Hyundai (they are called chaebol in South Korea), medium and small private businesses are the backbone of the country, like in any other advanced, market-oriented economy.
China does not have as many private businesses (proportionally) because it is not as populated, and because the government controls a larger part of the economy. In India, the economy is a lot poorer, and this makes it harder for private businesses to succeed.
The three rules known for unifying Japan are Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu.
