The answer to your question is type II
a positron emission tomography (PET) scan is an imaging test that allows your doctor to check for diseases in your body. The scan uses a special dye containing radioactive tracers. These tracers are either swallowed, inhaled, or injected into a vein in your arm depending on what part of the body is being examined
The Answer Would Be Pulling A Rope In A Tug-Of-War.
After reading the following options, the correct one is the third option, PET scans will use tracers to inject in a vein in someone's arm. Then, the organs as well as tissues will absorb the tracer. This information makes the third option correct because PET scans mostly work with your tissues to see if there are any diseases someone may have in their body.
Hope I helped! :)
