Considering the historical and cultural context of first-century Palestine, what is the MOST likely reason Jesus used parables as a primary teaching method?

A Parables were the only form of storytelling that the common people of Galilee could understand. B Parables allowed Jesus to subtly convey challenging spiritual truths to diverse audiences, including those who might have been hostile to direct confrontation, while also obscuring the message from those who were not spiritually receptive. C Parables were a convenient way for Jesus to avoid explicitly contradicting the teachings of the Pharisees and Sadducees. D Parables were primarily intended to entertain the crowds and distract them from their daily hardships.
