B Correct answer
Explanation

Let SP be the selling price of one pen. Loss = 3 * SP. Total SP = 72 * SP. Total CP = Total SP + Loss = 75 * SP. Loss percentage = (Loss / CP) * 100 = (3 * SP / 75 * SP) * 100 = (3/75) * 100 = 4%.

AI explanation

If the selling price of one pen is 1, the loss incurred on 72 pens is 3. This means the cost price for 72 pens was 75, since Cost Price equals Selling Price plus Loss. The loss percentage is calculated using the formula (Loss / Cost Price) * 100, which gives (3 / 75) * 100. The calculated result is 4%.
