B)Negative externalities.

Negative externalities are cost that is being suffered by a third party as a consequence of an economic transaction.

In a situation where a country has been turned into a dumping ground,foreign sells lower lower than the country's indegenous industries.This situation tend to discourage local industries from producing as they can't produce at such price .The government of such country can use a corrective tax policy by increasing the tax leveled on these imported goods and reducing tax on local industries.This will encourage exportation and discourage importation which is one of the parameters for economy development.

Explanation:

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
