Verified step by step guidance

Step 1: Begin by understanding the concept of 'metabolic inactivation.' This refers to the process by which the body chemically modifies a drug or compound to render it inactive, often through enzymatic reactions in the liver.

Step 2: Review the term 'feedback activation.' This is a regulatory mechanism where the product of a pathway enhances the activity of an enzyme earlier in the pathway. This is not related to drug inactivation.

Step 3: Examine 'allosteric inhibition.' This occurs when a molecule binds to an enzyme at a site other than the active site, causing a conformational change that reduces enzyme activity. This is unrelated to the metabolic inactivation of acetaminophen.

Step 4: Consider 'competitive inhibition.' This happens when a molecule competes with the substrate for binding at the enzyme's active site, preventing the substrate from being processed. This is also not relevant to acetaminophen's inactivation.

Step 5: Conclude that the correct answer is 'metabolic inactivation,' as it directly describes the process by which acetaminophen is converted to an inactive form in the body.
