Which of the following is a defined ACC/AHA adult BP category?

• A. Normal <120/80
• B. Normal <110/70
• C. Elevated 110-120/70-75
• D. Hypertensive crisis ≥180/120

Answer: (A)

ACC/AHA classifies adult blood pressure into defined categories, and normal is defined as a systolic reading under 120 and a diastolic reading under 80. That makes the statement describing normal blood pressure as <120/80 the correct description of the normal category. The other options don’t fit the official scheme: there isn’t a defined category called “Normal” with <110/70, the elevated category starts at 120–129 systolic with diastolic <80 (so 110–120/70–75 doesn’t match elevated), and a hypertensive crisis is defined as ≥180/120, which is a dangerous level, not a normal BP category.
