Economic inequality is the unequal distribution of the incomes and opportunities within the socioeconomical groups. For example, in every urbanized city, you can see homeless people amd poverty just a few meters from the skyscrapers. It is a common problem today, and it concerns almost every government.
B is likely the correct answer.
There are very few economists who advocate for the privatization of the military as the privatization of military has interesting efficiency and national security concerns. (Militaries in the hands of CEOs...)

Is there Any answer choices
Due to the lack of the choices, let me just give you here the definitions of appositional and interstitial growth.
Appositional growth happens when the inner layers of the cell divides into chondroblasts, increasing the cartilage mass.
Interstitial growth happens when the chondroblasts in the cartilage divide to form new small groups of cells.
