Robert Sternberg's triangular theory of love identifies passion, intimacy, and commitment as three components that shift in emphasis as romantic relationships develop.

Explanation:

According to Robert Sternberg's triangular theory of love, there are three basic components that make up love relationships: intimacy, passion and commitment. Passion in a couple relationship refers to the desire or need for union with the other member of the couple. According to Sternberg, it is the "burning component" of the relationship, thereby referring to the sexual desire they experience in a relationship for each other. Intimacy is related to those feelings and behaviors that bring us closer to the other person. Commitment refers to the decision to maintain a relationship with a person, to remain united both in good times and in bad times. Sternberg notes that each of these components evolve differently over time. Intimacy develops gradually as the relationship progresses and can continue to grow, although it is in its beginnings when it grows faster. The passion grows vertiginously, intensely and quickly in its beginnings but with the passage of time it decreases, reaching stabilize at moderate levels. Finally, engagement tends to grow slowly and stabilizes when the rewards and costs of the relationship appear clearly.

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).
