The passage above is a quote from the book of Acts in the Bible. In the passage, Peter is declaring to the Jews that God has made Jesus both Lord and Christ, and that they had crucified him. The question then asks what the Jews' reaction was to this declaration.

Option A states that the Jews decided to kill Peter and the apostles. However, this is not the correct answer. While the Jews had been known to persecute and kill early Christians, this particular passage does not mention any such reaction.

Option B states that the Jews went back to their houses in anger. Again, this is not the correct answer. The passage does not mention any particular emotional reaction from the Jews.

Option C, which is the correct answer, states that the Jews were deeply troubled and asked what they should do. This is a more accurate representation of the Jews' reaction, as the passage specifically states that they were "cut to the heart" and asked Peter and the other apostles what they should do in response to this news.

Option D states that the Jews ridiculed Peter and the apostles. This is not an accurate representation of their reaction, as the passage does not mention any ridicule being directed towards Peter or the other apostles.

In summary, the correct answer to this question is option C: the Jews were deeply troubled and asked what they should do. This passage highlights the importance of Jesus in Christianity and the impact of his crucifixion on the early Jewish community.
