He was actually horrified by them using gunpowder and even tells gulliver to not mention it to him again
We first need to understand what the Oedipus myth is to determine which of the statements is a fact. According to the play, Oedipus was doomed to kill his father and marry his mother, Because of this, his father ordered him be killed. This did not happen and he was abandoned and discovered by a neighboring king. When he was older, he was told this and fled the city to avoid the prophecy coming true. He meets Laius on the road, kills him, and then goes to Corinth, where he marries Laius' wife Jocasta. At the end of the play, Oedipus discovers that Jocasta is his mother and that he has murdered his father, causing him to pluck his eyes out and be exiled from the city because of his sins. With this in mind, we can say that the first choice, that Lauis and Jocasta are his parents, is the best answer here.
