What do "-opsy" and "-opsia" have in common?

The suffixes "-opsy" and "-opsia" both relate to processes involving examination or viewing, particularly in a medical context. For instance, "-opsy" is commonly found in terms such as "biopsy," which refers to the examination of tissue removed from the body to check for disease, especially cancer. Similarly, "-opsia" is used in terms like "opsia," which denotes visual conditions, such as "diplopia" (double vision). The commonality lies in the action of observing or examining through various medical procedures, both suffixes emphasizing the concept of investigation or assessment of a condition, particularly concerning tissue or vision.

The other options do not accurately capture the shared meaning of these suffixes. While some of the other options touch on related ideas—like vision or growths—they do not encompass the broader idea of examination or observation that both "-opsy" and "-opsia" convey in medical terminology.
