Final answer:
A cash payment made by an agent affects Line 7.0 which records total cash payments, and Line 8.3 which records agent payments specifically, on the DD Form 2665.
Step-by-step explanation:
When an agent or deputy makes a cash payment, it will impact specific lines on the DD Form 2665, which is used to document daily cash transactions in certain financial offices. The correct answer to which lines would be affected is d. Both a and b.
Line 7.0 records the total amount of cash payments made, so any cash payment would need to be entered here. Line 8.3 is used to record the total amount of cash payments made by an agent; therefore, when an agent makes a payment, it would also be recorded on this line.
It's important to note that being precise in filling out forms that deal with financial transactions is crucial to maintaining accurate records. Errors or omissions could lead to discrepancies in accounting and may have administrative or legal repercussions.
