To determine the average blood pressure (BP) for a 20-year-old from the given options, we need to identify common blood pressure norms for this age group.

2. ### Relevant Concepts

Average normal blood pressure for adults is considered to be around 120/80 mmHg. We will review the provided options and compare them to typical values.

3. ### Analysis and Detail

• Option a: 90/160 - This shows a very low systolic value, which is not typical.
• Option b: 120/80 - This aligns with the recognized average for adults.
• Option c: 80/120 - This has a wildly low systolic value as well.
• Option d: 160/90 - This reflects high blood pressure (hypertension).

4. ### Verify and Summarize

The most accepted average blood pressure for a healthy 20-year-old is indeed around 120/80 mmHg. Other values either indicate hypotension or hypertension.
