In medical terminology, which suffix indicates an instrument used to observe?

Explanation:
Observation with a device is signaled by the suffix that names an instrument for viewing. "-scope" comes from a root meaning “to look” and is used to name instruments designed to observe structures inside or outside the body, such as a microscope, otoscope, or endoscope. That direct link to viewing makes it the best fit for an instrument used to observe. By contrast, "-graph" refers to recording (a graph or trace), "-meter" to a measuring device, and "-itis" to inflammation, which isn’t about observation.
