Final answer:
The definition of a minor varies from state to state. Some states authorize 16-year-olds to consent to their own health care in certain circumstances.
Step-by-step explanation:
The definition of a minor varies from state to state. Some states consider a minor to be under 18 years old, while others have different age ranges. For example, some states authorize 16-year-olds to consent to their own health care in certain circumstances.
Therefore, it is incorrect to say that all states agree on the age a minor can consent to their own health care in all circumstances (option b).
