What is considered the safe range for adult blood pressure?

The safe range for adult blood pressure is typically considered to be between 90/60 mmHg and 120/80 mmHg. This range indicates normal blood pressure levels where the heart is effectively pumping blood and there are no significant risks associated with higher or lower readings. Blood pressure is categorized by two measurements: systolic (the top number, indicating pressure when the heart beats) and diastolic (the bottom number, indicating pressure when the heart rests between beats). Maintaining a blood pressure within this normal range is essential for overall health, as levels significantly above or below can lead to various health complications, including hypertension or hypotension.

The other ranges provided in the options may reflect levels that can be categorized as elevated or high blood pressure, which could pose health risks if maintained over time. Thus, the first choice accurately encapsulates what is recognized in medical guidelines as a safe and normal range for adult blood pressure.
