The normal blood pressure range for a healthy adult is typically recognized as around 90/60 mmHg to 120/80 mmHg. This range is established based on extensive research and clinical guidelines provided by health organizations. A systolic reading (the top number) of about 120 mmHg and a diastolic reading (the bottom number) of around 80 mmHg are considered optimal and indicate good cardiovascular health.

Blood pressure readings above this normal range can suggest hypertension, while readings below can indicate hypotension. The values within this range are crucial for assessing an individual's cardiovascular system's efficiency and overall health.

Other ranges provided in the options do not align with the established normal ranges in medical literature. Such discrepancies can lead to misinterpretations of a patient's health and inform incorrect treatment decisions.
