An Approving Officer (AO) may also serve as which of the following?

The correct choice indicates that an Approving Officer (AO) may serve as a convenience check custodian. This role aligns with the AO's responsibilities because both positions entail managing funds and ensuring that purchases comply with policy guidelines. As a convenience check custodian, the AO would have the authority to issue checks for specific, small purchases, thus augmenting their duties which are centered around overseeing the usage of the Government Purchase Card.

This is significant because both roles involve oversight of financial transactions and require a strong understanding of procurement policies. The AO's decision-making capacity in both positions helps maintain compliance with regulations and effectively manages budgetary constraints.

The other positions listed typically require distinct qualifications and are separate from the role of an AO, making them less appropriate for the same individual in this context. A Budget Analyst focuses primarily on financial analysis and budget preparation, a Contract Specialist is responsible for developing and managing contracts, and a Procurement Officer oversees larger procurement actions, which may not include the same breadth of duties as those of an Approving Officer or convenience check custodian.
