Step-by-step explanation:
The Defense Finance and Accounting Service (DFAS) provides finance and accounting services for the Department of Defense and other entities. When specifically considering the monthly accountability requirements for a Disbursing Officer (DISBO), the DISBO is required to submit a copy of the Monthly Statement of Accountability (SF 1219) to DFAS Indianapolis (DFAS-ZPFA/IN).
The correct answer to the question regarding the submission timeline is b) Within 10 calendar days of the end of the month. This means that the Disbursing Officer has a ten-day window starting from the first day after the month ends to ensure that the SF 1219 is submitted to the DFAS.
