Correct Answer: Option C

Let Cost Price of 1 article = 100. Cost Price of 5 articles = 500. Marked Price of 1 article = 150. Customer takes 5 articles but pays for 4. Selling Price of 4 articles = 4 * 150 * 0.80 = 480. Net Selling Price = 480. Net Cost Price = 500. Loss = 20. Loss percentage = (20 / 500) * 100 = 4%.
