What Effect Did the Confessional Booth Have

What effect did the confessional booth have?

A) It led to a serious decline in the participation of this sacrament, for Catholic believers did not trust being alone with their priests.
B) Since confession was now done privately and not in groups, many more priests had to be hired and trained.
C) It fostered a deeper internalization of spirituality for lay Catholics, for they had to face their spiritual advisers (priests) alone, not in groups.
D) A notable rise in complaints about inappropriate behavior by priests was registered.
E) Mass services were reduced, for priests had to spend so much more time in the confessionals.
