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.

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.

the answer to your question is,
