Reflecting on what you read in the course, what does it mean when a document or information is "privileged"?

The tax preparer who prepared the document or information is the only person who may authorize its disclosure.

The document or information is not relevant to the determination of the taxpayer's tax liability.

The IRS and other authorities may obtain and review the document or information, but they may not use it against the client.

The document or information is protected from discovery and use by the IRS.
