Answer:
A). Voluntary euthanasia.
Step-by-step explanation:
Voluntary euthanasia is demonstrated as the euthanasia(intentionally killing a human to free them from suffering or end their pain) that is performed with the full consent or permission of the patient as h/she is well-informed and aware of the direct and deliberate assisted sui-cide that they are going to suffer to end their life.
As per the question, 'voluntary euthanasia' occurs when the competent adult patient offers a 'fully informed request' to perform 'euthanasia' and determined to end their life deliberately to put an end to the acute suffering and miserable life. Thus, option A is the correct answer.
