Answer: B

Positive legal behavior refers to the activities performed by the actor in a positive way that directly affects the object, which is manifested in certain actions. Negative legal behavior refers to the activities performed by the actor in a negative and indirect way that affects the object, which is manifested as not taking certain actions. In most cases, the difference between positive behavior and negative behavior is that the former causes the object to change, while the latter keeps the object unchanged or allows or does not prevent the object from changing.
