Which flag is used with dpkg to find information about a specific package?

The flag used with dpkg to find information about a specific package is the option that allows users to display details regarding the package, including its version, architecture, dependencies, and other related metadata. When you include this flag along with the package name, it provides a comprehensive overview of the package's characteristics and status within the system. This command is particularly useful for understanding what a package entails and determining if it is correctly installed or has the necessary prerequisites.

The other options refer to different functionalities. While some also deal with package information, their specific purposes differ from the intention of seeking detailed information about a single package. Recognizing these distinctions allows users to effectively navigate and manage packages in a Linux environment.
