The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Food Preservatives**: - Food preservatives are substances added to food to prevent spoilage and extend shelf life. They inhibit the growth of microorganisms such as bacteria, fungi, and viruses. 2. **Identifying Common Preservatives**: - There are various food preservatives, but we need to identify the most commonly used one. 3. **Highlighting Sodium Benzoate**: - Among the various preservatives, sodium benzoate is noted as the most widely used. It is effective in preventing the growth of harmful microorganisms. 4. **Chemical Structure of Sodium Benzoate**: - Sodium benzoate is the sodium salt of benzoic acid. Its chemical structure consists of a benzene ring attached to a carboxylate group (COO-) and a sodium ion (Na+). 5. **Metabolism of Sodium Benzoate**: - When ingested, sodium benzoate is metabolized in the body. It reacts with glycine (an amino acid) to form hippuric acid, which is then excreted through urine or feces. 6. **Conclusion**: - Therefore, the most commonly used food preservative is sodium benzoate, as it not only preserves food but is also easily metabolized by the body. ### Final Answer: The most commonly used food preservative is sodium benzoate. ---
