Answer:
(A) a way to make a difference in something we care about.
Explanation:
This is what the textbook means when it defines public speaking as a form of empowerment. The fact that a person feels empowered means that they feel that their actions can truly make a difference. They have the "power" to change the circumnstances they do not like. This comes from the knowledge that public speaking can make a difference in something that they care about.
