Which of the following CIA triad concerns is violated when known-good computer hard drives and printed documents are placed in the trash?

Availability concerns the timely and reliable access to information by authorized users; simply trashing data does not inherently affect its availability to authorized users prior to disposal.

Placing known-good computer hard drives and printed documents in the trash makes the sensitive data contained on them accessible to anyone who sifts through the trash. This directly compromises confidentiality, which is the principle of preventing unauthorized disclosure of information.

Integrity ensures that data remains accurate, complete, and uncorrupted; placing items in the trash does not inherently alter or corrupt the data itself, but rather exposes it.

Accounting (also known as accountability or auditing) relates to tracking user activities and resource usage; improper disposal is a security lapse, not a failure of activity logging.
