Answer:
The answer is a. response generalization.
Step-by-step explanation:
Reponse generalisation occurs when a person presents similar behaviours to the target (or desired) behaviour, only in different places. In other words, the behaviours have the same function.
Another example is teaching a child to say "hello" when meeting a person. In time, the child may also start saying "hi" or "good morning" without direct teaching.
