Final answer:
The elderly obese woman would typically have the highest blood pressure readings.
Step-by-step explanation:
The group that would typically have the highest blood pressure readings is the elderly obese woman (option C).
Multiple factors contribute to high blood pressure, including age, weight, and overall health. Elderly individuals are more likely to have higher blood pressure due to the natural aging process and the increased risk of health conditions that can elevate blood pressure.
In the given options, an obese male teenager (option A) may also have high blood pressure, but it is less common in this age group compared to older individuals. A 45-year-old male runner (option B) and a 25-year-old office assistant (option D) are less likely to have high blood pressure in the absence of any underlying health conditions or risk factors. A 6-year-old child (option E) typically has lower blood pressure than adults.
