You want a team lead to be able to grant the admin, edit and view roles in their own namespace without holding those permissions themselves. Which verb makes that possible?

Answer: C. bind on the named ClusterRoles

Creating a binding requires either holding everything the referenced role grants or holding the bind verb on that particular role, which is how delegation is done without conferring the permissions themselves.
