Answer:
d. active
Step-by-step explanation:
In general, there are two types of euthanasia: active and passive.
In active euthanasia a person directly and deliberately causes the patient's death while in passive euthanasia they don't directly take the patient's life, they just allow them to die.
For active euthanasia, an act is required (for example, giving medications that will cause death), while in passive euthanasia the death is achieved by withdrawing the necessary treatment or conditions that keep the person alive.
In this example, Terry's caregiver takes the decision to end her pain by administering a lethal dose of a drug. Terry's caregiver is actively doing an act that will end with Terry's life. Thus, this is an example of active euthanasia.
