You have downloaded a file named file.tgz along with a signature file named file.tgz.asc. Which commands can be used to verify that file.tgz has not been tampered with since the file creator created…

The `gpg --verify <signature_file> <signed_file>` command explicitly instructs GPG to verify the integrity of the signed data file using the provided detached signature file.

`gpg verify file.tgz` is incorrect because it expects the file itself to contain an inline signature, not a detached one, and would not automatically search for `file.tgz.asc`.

When a signature file (e.g., `file.tgz.asc`) has a conventional name corresponding to its data file (e.g., `file.tgz`), `gpg --verify file.tgz.asc` can automatically locate and verify the data file against the signature.

`gpgv verify file.tgz.asc` is syntactically incorrect; `gpgv` itself implies verification, so the `verify` subcommand is redundant and not part of the `gpgv` syntax.

The `gpgv` command is a lightweight utility optimized for signature verification, and when given a detached signature file (e.g., `file.tgz.asc`), it will implicitly look for and verify the integrity of the corresponding data file (`file.tgz`).
