The major difference between Deng Xiaoping and Mao Zedong can be simply put that Deng Xiaoping was much more practical and realistic.
Deng Xiaoping was not extreme as Mao Zedong, and unlike Mao who closed the country to the world and implemented non-realistic terrible economic policies, Deng reformed the economy of China and opened it up to the world.
Deng started with the Four Modernizations, which included the agriculture, industry, technology, and science development. He opened up the country gradually to the world, and gave his best to modernize the country, catch the pace of the developed countries, and make China a strong nation. All of his policies were perfected to detail, they were realistic, practical, and very efficient, resulting in great prosperity and development in China very rapidly, making China the biggest producer of goods in the world, as well as one of the strongest nations in every aspect in the world. No wonder that he is often referred to as the ''Greatest economist in the human history''.
B: The Federal Government needs to respond quickly.
Congress needs to go through a long and careful process to get things done, not to mention them needing to have the majority of congress agree.
The president/executive branch of the government is made up of much less people, as well as the president himself being commander and chief of the military.
Time is very important during a national emergency, and the president can get things done quickly.
Hope this helps.

Since this answer depends on where you live, I'll just make a nice little example you can go off of! My little home has representatives such as but not limited to Lou Barletta, Ryan Costello, Glenn Thompson, Connor Lamb, Brian Fitzpatrick, and my favorite of all Mike Kelly. If it troubles you too much google your nearby representatives and what they do individually! Good day
I strongly believe the answer is C. Because they both became the richest and most powerful country.
