BAC stands for what measurement, with United limit 0.02%?

Explanation:
BAC is the percentage of alcohol in the bloodstream, a standard measure of how much alcohol is present in the blood and used to assess impairment. The best choice identifies this as Blood Alcohol Content, which is the correct term for what BAC represents. The idea of Blood Alcohol Consumption would imply a count of drinks or total intake rather than the concentration measured in the blood, so it isn’t the standard definition. Breath Alcohol Content would refer to a breath test result (BrAC), not the blood concentration itself. Baseline Alcohol Check isn’t a recognized term for this measurement. The United limit of 0.02% reflects the policy threshold for impairment, with the FAA commonly cited as 0.04% in other contexts.
