Answer:
Hengityksen hallinta tarkoittaa hellävaraista hengittämistä, vähäisimmällä vaivalla. Se auttaa, kun sinulla on hengähdystauko tai tunnet ahdistusta. Alla olevaa tekniikkaa opetetaan joskus joogassa.

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.
