Answer:
Option B, excessive
Explanation:
In medical terminology, the prefix hyper- often signifies something is above its expected "normal" amount or baseline value range.
The root word tension, refers to the blood pressure, in which the blood vessels of the circulatory system stretch to accommodate the force exerted against their walls by the blood with each heartbeat.
When attaching, the prefix to the root word, hypertension then describes the condition in the blood pressure is excessively high as compared to expected range.
Expected or average blood pressure for adults is considered to be 120/80, with close variations also deemed okay; some sources consider 130/80 to be expected blood pressure. Hypertension becomes a suspected diagnosis when the patient's blood pressure, when resting and without the presence of stressors, reads above 130 systolic (the top number) and 80 diastolic (bottom number).
In short, the prefix hyper- in the medical term hypertension means excessive, option B.
