If this is the Ancient Greek God Zeus then he would be thinking about how to govern Mount Olympus because that is where he is at the highest role such as having the most power and to rule and lead the people of Olympus.
From my knowledge, the Huang River is the birthplace of civilization in China. In fact, some of the most ancient settlements in Eastern Asia is situated on the banks of the Huang River. There is a Chinese cliché that says that "the Huang River is the cradle of the Chinese". Now to answer your question, the river provided a source of food and transportation, which encouraged early barter exchange throughout the small villages/tribes of ancient China.
Roads, canals, and railways were three major components of transportation improved during the first industrial revolution. People used the roads as the basic way to transport the goods from one place to another. Transporting goods by canal lowered the risks of smashed products during route.
I think the answer is C because other choices doesn't really make sense. Especially choice A. Hope this helped.
