"Period-End Closing": "The period-end closing utility transfers the balances of all P&L accounts to a balance sheet account that you define
for example
a retained earnings account. As a result
all P&L accounts have a zero balance at the beginning of the new posting period." (This directly supports answer C and refutes A).

"Chart of Accounts Window": "The chart of accounts is structured like a chest of drawers... The first three drawers contain the G/L accounts for assets
liabilities
and equity... The other five drawers contain the G/L accounts for revenues
cost of sales
expenses
financing
and other revenues and expenses (or non-operating income and expenditure)." (This directly refutes answer D).

Financial Accounting with SAP S/4HANA (While for S/4HANA
the core accounting principle is identical and universally applicable to SAP ERP systems including Business One): "At the end of the fiscal year
the balances of the P&L statement accounts are set to zero... The net profit or loss for the year is calculated from the balances of the P&L statement accounts. This net profit or loss is then posted to an equity account (retained earnings)." (Chapter 3
Section 3.2.2
G/L Accounts). This confirms the fundamental accounting principle behind answer C.
