Explanation

On Red Hat-based Linux systems (RHEL, CentOS, Fedora), individual YUM/DNF repository configuration files must be placed in the /etc/yum.repos.d/ directory with a .repo file extension. The package manager automatically scans this directory and loads any file ending in .repo. Option A reflects this convention - note that the exam question contains a minor typo ('reps' instead of 'repos'), but among the four choices it is the only one that includes the required .repo file extension, making it the best answer. Option B uses an incorrect path with an underscore and no .repo extension. Option C uses the same typo but critically omits the .repo extension, which would cause the file to be ignored by yum/dnf. Option D (/etc/yum.conf) is the main yum configuration file for global settings, not the appropriate location for individual repository definitions.
