Answer:
Option (D)
Explanation:
Physiological density refers to the number of people that are present per unit area of land that are used for the agricultural purpose. It is also known as the population density. Whereas, the agricultural density refers to the number of farmers present per unit area of land that are used for farming.
The machines are generally used when there is less man-power. But at the same time, using machines are also costly.
So, in a country where there is a huge amount of population and huge number of farmers, there the machineries are not used. The manpower is sufficient enough to cultivate the lands and grow crops.
For example, a country with high physiological density and agricultural density is India.
Hence, the correct answer is option (D).
