Who may respond to inquiries about a specific acquisition?

The contracting officer with contractual authority is the correct answer because this individual has the legal responsibility to manage and oversee contracts and procurement processes. They possess the necessary training and authority to respond to inquiries regarding a specific acquisition, ensuring that the information provided is accurate and compliant with applicable laws and regulations. The contracting officer is the designated representative who can discuss contractual terms, conditions, and any potential impacts or clarifications related to the acquisition.

In contrast, while the program manager or project lead may have substantial knowledge about the project's requirements or objectives, they typically do not have the same level of authority or the capacity to make binding commitments pertaining to the contract. Administrative assistants usually help with logistical support and communications but lack the contractual authority to address inquiries regarding specific acquisitions. Therefore, the role of the contracting officer is pivotal in safeguarding the integrity of the contracting process and ensuring that inquiries are handled appropriately.
