Question 200
Refer to the exhibit. An engineer must configure a load balancer server. The engineer prepares a script to automate workflow by using Bash.

Based on the script workflow, which process is being automated within the loop by using the information in sites.txt?
A. creating a file per each line in sites.txt with the information in template.conf, creating a link for the previously created file, and then changing the ownership of the created files
B. using the content of the file to create the template.conf file, creating a link from the created file to the /etc/nginx/sites_enabled, and then changing the file execution permissions
C. creating a new file based on template.conf in the /etc/nginx/sites_enabled directory for each line in the sites.txt file, and then changing the file execution permissions
