Opportunity cost should be recorded as : 1- An income statement account . 2- A balance sheet account . 3- Another option .

opportunity cost is not recorded in any financial statements. However such computation is important in decision making for management purposes.

Opportunity cost  is not  recorded in financial statements 

You can put it in normal cost report used internal by company managment 

Opportunity cost is not an income that you can get or an expense that you spend , its the benefits you could have received by taking an alternative action. so its unrecorded.

it's economic indicator not financial profit , that help decision maker to compare with other alternatives'

Opportunity cost should not be recorded in the company accounts but the manager should put it  in consideration on decision-making

Agree with the given answer.

opportunity cost should not be recorded as any where , it is considering only for decision making purpose

not record because it is non cash - expenses / profit   

Opportunity cost should not be recorded in income statement or balance sheet, but Opportunity cost is cost of an alternative that must be forgone in order to pursue a certain action. Put another way, the benefits you could have received by taking an alternative action.

Example. If we have £20 we can spend it on an economic textbook or we can enjoy a meal in a restaurant. If we spend that £20 on a textbook, the opportunity cost is the restaurant meal we cannot afford to pay.
