Final answer:
Factors that may impact a person's blood alcohol concentration (BAC) include the amount of food consumed, rate of alcohol consumption, and individual metabolism.
Step-by-step explanation:
All of the above factors, including the amount of food consumed, rate of alcohol consumption, and individual metabolism, can impact a person's blood alcohol concentration (BAC).
When alcohol is consumed on an empty stomach, BAC can rise more quickly compared to when alcohol is consumed with food. The rate of alcohol consumption also affects the peak BAC, as drinking alcohol quickly can lead to a higher BAC.
Additionally, individual metabolism plays a role, as some people metabolize alcohol more efficiently than others, leading to differences in BAC levels.
