Answer:
b. Hector and Felix are not engaged in conflict because conflict must be expressed.
Step-by-step explanation:
It is mentioned in the statement that Felix is in fact angry with his roommate Hector, for playing loud music but hasn’t express his feelings yet to him. We can infer that Hector has no idea that Felix is angry at him, so in consequence, there is no conflict between Hector and Felix; because there is no conflict for Hector; there is only conflict only for Felix. In order to the conflict to be real, Felix should state his problem and tell what he thinks to Hector and start an arguing conversation.
