Which of the following terms represents an abnormal condition?

The suffix "-osis" indicates an abnormal condition or disorder, often characterized by an increase or accumulation of certain substances or cells in the body. For example, in medical terminology, conditions like "nephrosis" (an abnormal condition of the kidneys) or "dyscrasia" (abnormal condition of the blood) fall under this category. This suffix helps to convey that something is not functioning normally or is present in excess, which is why it is the correct choice in this context.

While the other terms have specific meanings that can relate to conditions, they do not universally denote an abnormal status. For instance, "-oma" typically refers to a tumor or benign growth, "-sarcoma" denotes a malignant tumor derived from connective tissues, and "-stasis" refers to standing still or stable condition, which does not inherently imply abnormality. Therefore, "-osis" is uniquely suited to signify an abnormal condition in medical terminology.
