A) Children under 12, under special circumstances, may give consent:
In medical settings, especially involving serious procedures or treatments, children typically cannot provide informed consent without parental or guardian approval. There might be specific cases where mature minors, regardless of age, can provide consent, but this is generally determined by the individual's capacity to understand the implications of the decision.

B) Children under 12 are not allowed to be organ donors:
The ability for children under 12 to be organ donors is determined by various factors, including the specific organ, medical suitability, and the consent of parents or legal guardians. In some situations, organs from pediatric donors can be used for transplantation.

C) Children under 12 cannot be placed on an adult transplant list:
The decision to place a child on an adult transplant list depends on several factors, such as the severity of the medical condition, organ availability, and compatibility. Children can be placed on adult transplant lists in some cases, especially when there are medical considerations that make it necessary.

D) Children under 12 are not allowed to make decisions for themselves:
Children under 12 usually lack legal capacity to make major medical decisions without parental or guardian consent. In specific situations, mature minors might be involved in medical decision-making, but this is determined on a case-by-case basis and varies by jurisdiction.

Egoism: Egoism is an ethical theory that emphasizes self-interest as the motivation for human behavior. It suggests that individuals act in their own self-interest and seek to maximize their own happiness or well-being.

Utilitarianism: Utilitarianism is an ethical theory that states the best action is the one that maximizes overall happiness or pleasure. It focuses on the consequences of actions and aims to achieve the greatest good for the greatest number of people.

Deontological: Deontological ethics, also known as duty-based ethics, focuses on the inherent nature of an action, rather than its consequences. It suggests that some actions are inherently right or wrong, regardless of the context or outcomes.

Jurisdictional: Jurisdictional refers to the legal authority or power of a court or other governmental entity to make decisions and judgments within a specific geographical area or in a particular legal domain. It does not directly relate to ethical decision-making principles.
