Answer: C

Explanation:

A file policy defines the actions that the Cisco Firepower Threat Defense (FTD) device should take when it encounters different types of files. The file policy is applied as part of an access control policy. If an access control policy does not include a file policy, the FTD device will not take any action on the files it encounters, resulting in a disposition of "unknown" for all file types except exe.
