Final answer:
Group policy settings can be applied to Users, Computers, and Organizational Units (OUs) directly within an Active Directory environment. Groups as an object are not directly applied to, but members are affected when they belong to an OU with an active policy.
Step-by-step explanation:
Group policy settings apply to multiple objects within an Active Directory environment. Specifically, they can be applied to the following:
- Users: Group policies can be used to control the environment of user accounts, such as desktop settings, security settings, and software installation.
- Computers: Group policies can manage computer accounts, affecting settings like security policies, network configurations, and system services.
- Groups: While not directly applied to security groups, group policies can affect members of a group when linked to an OU that contains those users or computers.
- Organizational Units (OUs): Group policies are often linked to OUs to apply settings to a collection of users, computers, or other OUs within the Active Directory.
Options A (Users), B (Computers), and D (OU) are where group policies can be directly applied. Option C (Groups) is not directly applied but is affected through membership in OUs with linked group policies.
