If we were to critique Kant as not caring about the effects or outcomes of moral actions, :

a) we would point out that Kant's moral philosophy generates the many-formulations problem.
b) we would be citing the consequences of the problem as a serious problem for Kant's moral philosophy.
c) we would be claiming that Kant's moral philosophy faced the absolutism problem.
d) we would be saying that Kant's moral philosophy suffers from the rational agent's problem.

The correct answer is letter A

Kant's moral doctrine is independent of any religious sense. Its morality excludes the notion of intention as an element of a pure soul, and duty is not an obligation to be followed by virtue of a superior being. Intention and duty (in Kant) depend on the epistemological subject (transcendental self) and not on the psychological self (individual). For Kant, the transcendental subject is a subjective, universal and necessary machinery (cognitive apparatus) (present in all men, in all times and in all places). Thus, every healthy being has such an apparatus, formed by three fields: reason, understanding (categories) and sensitivity (pure forms of intuition-space and time).

In Kant, the reason (faculty of ideas) is that it preserves the principles that articulate intention and duty according to the subject's autonomy. Thus it follows that such principles cannot be denied without self-contradiction. Hence the idea of Kantian freedom, a priori synthetic character, and without freedom there can be no moral act; to be free, we need to be bound by the duty to be free.

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).
