Answer 1

In a use case diagram, a solid line with an arrowhead from an actor to a system boundary typically represents an Association. This type of association indicates a relationship between an actor (external entity interacting with the system) and the system boundary (representing the system). This association shows that the actor is involved in interactions with the system.
