Answer: C.expressing disapproval.
In this "apology," Socrates describes his role in Athenian society. He had been accused of corrupting the youth and condemned to commit suicide. However, he is defending his role as a philosopher by saying that he is the one who reminds both the government and the people of their duties. He states that he considers it his duty to always be "arousing and persuading and reproaching" them. In this case, "reproaching" means expressing disapproval at their actions.
