which of the following is a disadvantage of retailing

The correct option is "selling on credit" and this is because it can lead to the accumulation of bad debts which may eventually lead to the collapse of the retail business. When a retailer sells goods on credit, it means they are allowing the customer to take the goods without making immediate payment, with the expectation that the customer will pay later. However, if the customer fails to pay or delays payment, the retailer may have to incur costs to recover the debt, which can be a financial burden on the business. This can also cause cash flow problems and make it difficult for the retailer to pay their own bills and suppliers, ultimately affecting the sustainability of the business.
