The correct answer is A. Cash . In the traditional ordering of current assets on a U.S. balance sheet, accounts are typically listed in order of liquidity , meaning how quickly they can be converted into cash or used. Cash is already the most liquid asset, so it normally appears first. After cash, companies usually list items such as marketable securities, accounts receivable, inventory, and prepaid expenses. OpenStax identifies cash among the standard examples of assets and discusses current assets such as accounts receivable, inventory, and prepaid items.
Option B, inventory , is incorrect because inventory is less liquid than cash and receivables. Option C, accounts receivable , is also incorrect because receivables are expected to become cash, but they are not cash itself. Option D, prepaid expenses , typically appear later because they do not convert into cash; instead, they provide future benefits through services or coverage already paid for. In U.S. practice, the standard presentation begins with the most liquid current asset, which is cash. Therefore, among the choices provided, Cash is the correct answer.
