The liver processes alcohol at an average rate that reduces blood alcohol concentration (BAC) by about 0.015–0.016% per hour , so from the options given, 0.016% per hour is the best answer.

Correct option

  • Typical teaching value: the liver lowers BAC at about 0.015 g/100 mL per hour , often rounded to 0.016% per hour.
  • Therefore, among .016% .008% .032% .064% , the closest to the standard metabolic rate is 0.016% per hour.

Helpful context

  • Many health and university sources explain that after alcohol peaks in the blood, BAC falls at a relatively steady rate of around 0.015–0.016% per hour , regardless of tricks like coffee or cold showers.
  • Factors like body size, sex, liver health, and medications can make the actual rate a bit slower or faster for a given person, but teaching materials and exam questions typically expect 0.016% per hour as the standard value.

TL;DR: For “at what rate does the liver process alcohol per hour?” the expected test answer is 0.016% per hour. Information gathered from public forums or data available on the internet and portrayed here.
