Selected Answer: D

The correct answer is D. REQUIRES=mariadb.service. The REQUIRES directive in systemd tells systemd that the HTTP server service depends on the mariadb.service service. This means that systemd will not start the HTTP server service until the mariadb.service service is started and running.
