The correct answer is: 0.08

The legal blood alcohol concentration (BAC) limit for drivers over the age of 21 in California is 0.08. This means that the percentage of alcohol in the blood cannot exceed 0.08% while driving. Option A (0.01) is incorrect because this is the BAC limit for drivers under the age of 21 in California. Option C (0.04) is incorrect because this is the BAC limit for commercial drivers in California. Option D (0.02) is incorrect because this is the BAC limit for drivers who are on probation for a previous DUI offense in California. It is important to note that these BAC limits may vary for different states or countries.
