Answer:
A. For every single transaction, at least two accounts will be
affected.
Step-by-step explanation:
Double-entry accounting is a record-keeping method where a transaction is recorded in a minimum of two accounts. There is no upper ceiling on the actual number of accounts that may be used in a transaction.
Every account has two columns, with debits on the left and credit entries on the right. The aggregate of the debit entries must equal the result of all credit entries. If this happens, the transaction has balanced. If not, the transaction is "out of balance."
