Which set of vital sign ranges accurately describes normal adult values?

Explanation:
Understanding normal resting vital signs for an adult is the key idea here. The standard reference ranges are roughly: heart rate 60–100 beats per minute, blood pressure about 100–120 systolic / 60–80 diastolic, and respiratory rate about 12–20 breaths per minute. The set that lists all three of these ranges together matches those widely accepted reference values, making it the best choice. This combination reflects a typical resting state in healthy adults and is what clinicians use as a baseline when assessing stability. While individual values can vary with age, fitness, medications, or health conditions, any option that shifts any of these numbers outside the common 60–100, 100–120/60–80, and 12–20 ranges is moving away from the standard normal for most adults.
