B
Correct answer
Explanation
The normal blood pressure reading is 120/80 mmHg, which is considered the standard healthy blood pressure. This represents systolic pressure of 120 and diastolic pressure of 80. The other options are incorrect: 140/90 is considered high/prehypertension, 120/89 doesn't follow standard notation, and 140/80 is not the normal reading.
