Best answer
The correct choice is (b) Gadolinium

The best explanation: Bismuth germinate oxide (BGO), gadolinium oxyorthosilicate (GSO) or lutetium oxyorthosilicate detectors (LSO) are three materials that can be used to form the detectors for PET. They can record impulses from the gamma rays and convert them into electrical signals which are finally processed to form images.
