The correct answers are B. Roles and Subordinates, C. Public Groups, and D. Users / Individual Users.
Salesforce manual sharing allows record owners or users with proper access to share individual records with users, public groups, and roles. Salesforce documentation specifically states that manual sharing is used to share individual records with other users, public groups, and roles.
For Lightning manual sharing, Salesforce also describes entering groups, users, roles, or territories in the sharing search box.
So, based on your option wording:
B appears to mean Roles and Subordinates.
C is Public Groups.
D appears to mean Users / Individual Users.
A. Permission Set Groups is incorrect because permission set groups grant object, field, app, and system permissions, not case-by-case record sharing.
E. Private Groups is not the standard answer for this Platform App Builder manual-sharing question.
