1. The problem asks: Which term represents the percentage charged by a money lender on borrowed money? 2. Option A: "interest" is the amount paid as a fee for borrowing money, usually a percentage of the principal. 3. Option B: "inflation" is the rate at which the general level of prices for goods and services rises, reducing purchasing power, not related to direct charges by lenders. 4. Option C: "interest rate" is the percentage charged on the borrowed amount; it directly represents how much extra money must be paid. 5. Option D: "tax" is a government levy, unrelated to money lending charges. 6. Therefore, the correct answer capturing the percentage charged by lenders is option C: interest rate (rentekoers).
