Answer:
A : Net income will be understated and
F. Assets will be understated on the balance sheet.
Explanation:
'Billed customers $1,400 for services performed' will be journalised as:
Cash A/c Dr to Sale/Income A/c Cr.
So; Not recording this transaction will understate the income & asset i.e cash. Income will be understated in the P&L A/C, assets will be understated in the Balance Sheet.
Other options are inapt because: Assets & Income overstatement are opposites of correct answer. Journal & ledger will be balanced because the entire entry is not recorded & its both debit & credit aspects have been omitted.
