Which of the following is an asset?

An asset refers to something of value that is owned by a business or an individual and can be used to generate income or cash flow. In the context of farm and agribusiness, assets can include both tangible and intangible items that contribute to the business's operations and overall value.

A fence qualifies as an asset because it has physical value and contributes to the functionality and security of the farm. It is a structural element that can help protect crops, livestock, or facilities and thus supports the overall operation and productivity of the farm.

The other choices do not represent assets in the same direct manner. For instance, the account balance at a farm supply store represents a liability or an obligation to pay for supplies, while the sale of corn is a transaction that can increase revenue but does not constitute an asset itself. Lastly, net worth is a measure of the overall financial position of the business but is not a specific asset. It reflects the total value of assets minus liabilities, rather than being an asset in itself.
