Concept:A profit and loss account summarises the farm's income and expenses over a full financial year.
Explanation:At the end of the year, the farm prepares a profit and loss account to show whether it earned a profit or incurred a loss.
Other documents like the farm budget and labour record are made during the year, not at the end.
A farm inventory records items at a particular date, but it is not the year-end summary of financial performance.
Therefore, the document usually prepared at the end of the year is the profit and loss account.
Answer:D. profit and loss account
