To determine the correct answer, let's analyze the options:

A. Moral duties override moral rights.
B. Moral rights override moral duties.
C. The existence of moral rights implies duties by which others must abide.
D. None of the above.

The concept of correlativity of rights and duties suggests that rights and duties go hand in hand, implying that they are mutually linked. One cannot have rights without corresponding duties, and vice versa.

Option A states that moral duties override moral rights. However, this contradicts the fundamental principle of correlativity, as it suggests that duties are more important than rights. Therefore, Option A is incorrect.

Option B suggests that moral rights override moral duties. This is also contrary to the concept of correlativity, as it implies that rights are more important than duties. Hence, Option B is incorrect.

Option C proposes that the existence of moral rights implies duties that others must abide by. This aligns with the concept of correlativity, as it acknowledges the reciprocal relationship between rights and duties. When individuals have certain moral rights, others are obligated to fulfill corresponding duties. Therefore, Option C seems to be the most accurate choice.

Finally, Option D states that none of the above answers are correct. This option does not provide any specific alternative and does not seem to represent a valid response.

Based on this analysis, it appears that Option C, "The existence of moral rights implies duties by which others must abide," is the most suitable answer.
