Final answer:
Peter the Great's attempts at westernization likely improved his people's opinion of Western Christians due to cultural exchange, although some resentment may also have existed because of the forced adoption of foreign customs. Option a.
Step-by-step explanation:
Peter the Great's attempts at westernization probably had a complex impact on his people's opinion of Christians in Western Europe. While forced cultural changes can engender resentment, shared religion and admiration for technological and cultural advancements can also improve relations.
However, in this case, the most likely outcome would be option (a): Improved their opinion due to cultural exchange.
Peter the Great's efforts to modernize Russia through Western technologies and customs, including dress and the organization of the military and government, could have made Western Christians appear as sophisticated role models. However, this admiration could be mitigated by the resentment of the forced adoption of foreign customs.
Overall, cultural exchanges during Peter's reforms likely created a mix of respect for some aspects of Western Christian society, curiosity about their advancements, and resentment of the pressures to conform to foreign ways.
So option a is correct.
