Answer: Option (A) is correct.
Explanation:
Correct Option: Normal profits because economic profits will attract new firms and there are no entry restrictions.
In a monopolistically competitive market, firms will earn an economic profit in the short run, so new firms attracted with these profits and decided to enter into the market in the long run.
There is no barriers on entry and exit of the firms in the monopolistically competitive market. When new firms enters into the market, as a result supply of differentiated products increases.
This causes the firm's market demand curve to shift leftwards. It will continue shifting to the left in the firm market demand curve till the point where it is nearly tangent to the average total cost curve.
At this point, firms earns zero normal profit and can earn normal profits in the long run same as a perfectly competitive firm.

In calculating, GDP, we have expenditure approach, income approach and value-added approach.
In this question, the expenditure approach will be used to explain the answer to this question.
To calculate GDP using expenditure approach, the formula is:
C + I + G + (X-M)
where C is the consumers' spending
I is the investment spending
G is government spending
X is the exports
M is the imports.
The correct answer is C. firms purchases of inventories is part of investment spending. Firms can purchase raw materials(inventory) and process it into finished goods(inventory). The change in inventory(difference between the closing inventory and opening inventory) is part of the calculation of investment spending.
Households buying inventories(finished goods) is part of consumers' spending and not investment spending.
Answer:
False
Explanation:
A proposed trade of 12.5 pounds of butter for 20 guns may NOT be mutually agreeable to both countries.
The main idea of comparative advantage is NOT trade by barter but buying and selling. Comparative advantage is a principle that states that a country should produce more of the goods and services which it can produce at a lower opportunity cost than that of trade partners and thereafter sell to those partners at a lower cost than they would have produced it themselves in the bid to be self reliant.
It is difficult to agree to such a deal of 12.5 pounds of butter for 20 guns because it is impossible to conclude that they are even or equal in value. The both countries should sell to each other as money is a common means of exchange.
