Final answer:
Accounts receivable is considered the most liquid as it can be easily converted into cash.
Step-by-step explanation:
Accounts receivable is considered to be the most liquid out of the given options. Liquidity refers to how quickly a financial asset can be used to buy a good or service. Accounts receivable represents money owed to a company by its customers for goods or services already delivered, and it can be easily converted into cash by collecting payment from customers. Land, equipment and machines, and inventory are all less liquid assets as they are not as easily converted into cash.
