The NACI, or National Agency Check with Inquiries, investigation is a background check primarily used to determine eligibility for access to classified information or to perform duties that require a certain level of trustworthiness. This investigation applies to both civilian employees and contractors who need access to government facilities or information.

The significance of this investigation lies in its comprehensive nature, which includes checks against various databases to uncover information about an individual’s character, conduct, and loyalty. Since both civilians and contractors can have roles that necessitate this level of certification, it's crucial that the NACI investigation encompasses both groups. This ensures that anyone operating in sensitive environments or handling sensitive information meets the required security standards.

To understand the context of the other choices, the military typically undergoes different types of investigations more specific to their roles, while civilians and contractors indeed fall under the purview of NACI requirements because of their potential access to sensitive government work.
