The correct answer is d. I, II and III.
All three items listed are typically included in a monthly checking account statement:
I. A period (beginning date and ending date) - The statement covers a specific time frame. II. A beginning balance and ending balance - These indicate the amount in the account at the start and end of the period. III. A detailed list of debits and credits during the period - This includes all transactions that occurred within the statement period.
Therefore, all three elements are present in a typical monthly checking account statement.
