The right option is; d. 366 people/mi^2

Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.  

From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.

Population Density = Number of People / Land Area.

Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.

Therefore, the population density of China is 366 people per square mile.
