Answer:
A. Is generally accepted for external reporting because it gives more useful information.
Step-by-step explanation:
Accrual Basis of Accounting states that: Transactions should be recorded when they are entered into, irrespective of cash settlement done or not.
For Eg: 'Sales' would be recognised & recorded when goods are sold & debtor's obligation / liability to pay has been established, whether cash has been received or not.
This basis of accounting provides a clearer picture of enterprise' performance during an accounting period (i.e financial year), by providing for the real expenses & revenues of that period only.
Eg: Outstanding Expense (due but not paid) if ignored on cash basis - would lead to underestimation of expenses & overestimation of profit.
So, Accrual System is generally accepted because it is more 'Relevant' i.e more useful to Accounting information users.
