You have an updated RPM called screensaver-1.1.i386.rpm. You have version 1.0 installed.
Using RPM, how do you view the changelog of this file to see if you should install the update?

A.
rpm -qp –changelog screensaver-1.1.i386.rpm

B.
rpm –changelog screensaver-1.1.i386.rpm

C.
rpm -qc screensaver-1.1.i386.rpm

D.
rpm -showchangelog screensaver-1.1.i386.rpm

Explanation:
When you use rpm with a specific rpm-file, you need to specify the -p option, and the query-option to show the changelog is –changelog.
-qc would list the config files of an installed package (not an rpm-file)
–changelog on its own is an invalid option as is -showchangelog
