Which of the following concept stipulates that accounting profit is the difference between revenue and expenses?

The concept that stipulates that accounting profit is the difference between revenue and expenses is the accrual concept. Under this concept, revenues are recognized when they are earned, regardless of when the payment is received, and expenses are recognized when they are incurred, regardless of when the payment is made. This means that revenue and expenses are recorded in the accounting period to which they relate, rather than when the cash is received or paid out. This allows for a more accurate and fair representation of the financial performance of a company, as it takes into account all the transactions that have occurred during the period, rather than just those for which payment has been received or made.
