Explanation:

To determine the inaccurate statement about BAC:

• Option B: BAC does vary between individuals (due to weight, metabolism, etc.), so this is accurate.
• Option C: BAC is a standard measure of intoxication level, so this is accurate.
• Option D: BAC is defined as the concentration of alcohol in blood, so this is accurate.
• Option A: BAC reflects alcohol concentration, not directly the number of beverages (since factors like drink type, time, and individual differences affect BAC independently of beverage count). Thus, A is inaccurate.

Answer:

A. BAC is used to determine number of beverages consumed.
