The current assets among the given options are: Stock, bills receivable, cash, and debtors.
Current assets are those assets that can be easily converted into cash within a short period, usually within one year. They are assets that are expected to be consumed or converted into cash in the normal course of business operations.
Stock, also known as inventory, refers to the goods that a company sells or intends to sell. Bills receivable are the written promises by customers to pay for the goods or services provided by the company. Cash is the most liquid asset and includes money in hand, money in the bank, or any other highly liquid investments. Debtors are customers who owe money to the company for goods or services that have been delivered but not yet paid for.
All of these assets are expected to be converted into cash within a relatively short period of time and are therefore considered current assets.
In contrast, bad debt and work-in-progress are not considered current assets because they are not easily convertible to cash or are not expected to be consumed within a year. Bills payable are a liability, not an asset.
