The correct answer is C. collective bargaining
Explanation
Collective bargaining is a way of reaching an agreement within a group of people. Collective bargaining is generally used to establish in common agreement a position of a community to present its opinion in a specific situation, also, these groups usually have a representative who collects the opinion of all the members and expresses it in front of the counterpart to negotiate for all its represented. In the case of the question, the way of bargaining of the union of the company to which George belongs was collective bargaining, because George expressed his opinion to the union representative by saying that "George works in a factory and is a member of the labor union. He thinks his wages are low for the work that he does, so he tells the union representative that his employer should increase his wages". Likewise, his colleagues did so asking for a salary increase when the author states that, "The representative asks the other workers if they feel the same, and they all agree" and then the representative negotiated it with the employer who finally acceded to his request "The following week, the union representative met with the factory owner regarding an increase in wages, and the employer agreed to it". Therefore, the correct answer is C. Collective Bargaining.
