The correct answer is - True.
The Christianity was still dominant during the period of the Renaissance. The most significant intellectuals, scientists, of this period were all Christians. Despite their passion for science, these intellectuals were Christian followers and they did not had anything against the religion itself, they just opposed the church as an institution.
Lot of these intellectuals found it very hard because the church was still very powerful and was doing everything it can to stop them, be it with threatening, imprisoning, or even execution. Some though were undercover intellectuals if we can refer to them like that, as they were part of the church, did not opposed it, but also used it as their protection and working in private without having any particular problems.
