Answer:
The correct answer is letter "C": Due to the trust relationship between parent and child domains, any one domain can have access to the resources of all others.
Explanation:
Domain names are useful to recognize IP addresses -yahoo.com, for instance. All the equipment sharing at least part of the IP address is said to be under the same domain. A domain controller is a machine where the domain is installed. Then, a child domain is another domain inside the main domain also called the parent domain. As the child domain is subject to the parent domain, they both have access to the information shared between one another.
