The Korean War reached a point where neither side could gain an advantage over the other. This is known as a

Seesaw conflict

Explanation:

In the Korean war was fought after the World War II. The Korea war was fought between the North Korean which was supported by the Soviet Union and by South Korean led by the US troops. During the last one and a half year of the war, neither side was able to gain an advantage in the war.

In the year 1950, North Korea invaded South Korea. Neither of the party could gain an advantage in the war as there was a seesaw from south to north and again from north to south. Thus neither of the side could gain an advantage in the war.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
