The correct answer is C. apt-cache depends package.

When installing or removing packages in Debian-based systems using the dpkg package manager, dependencies can become a concern. Dependencies are other packages that a package requires in order to function properly.

The apt-cache command is used to search the local package database, and can be used to query package information, including dependencies. The correct option to list the dependencies of a given dpkg package is apt-cache depends package. Here's what the other options do:

A. apt-cache depends-on package is not a valid command. There is no "depends-on" option for the apt-cache command.

B. apt-cache dependencies package is a valid command, but it does not list the dependencies of a package. Instead, it lists the reverse dependencies, which are packages that depend on the given package.

D. apt-cache requires package is not a valid command. There is no "requires" option for the apt-cache command.

Therefore, the correct option to list the dependencies of a given dpkg package is apt-cache depends package.
