The Jansenists supported

A) the strict restriction of scientific investigation in France.
B) the enforcement of ecclesiastical overview of all scientific publications.
C) the refusal of all funds from the monarchy to support any scientific research.
D) the process of scientific discovery and debate.
E) the belief that all scientific investigation must be in line with Church teaching.

The Jansenists believed in the process of scientific discovery and debate, which would imply support for scientific investigation. They did not advocate for the restriction of scientific investigation or the enforcement of ecclesiastical oversight of scientific publications. There is no evidence to suggest that they refused funding for scientific research or believed that all scientific investigation must be in line with Church teaching.
