What did father Flynn do or say that gets Sister James to believe in his innocence? Movie - Doubt

As for Sister Aloysius I think she doubts not one single doubt. She was doubting whether she did the right thing, doubting whether Fr. Flynn was guilty and most importantly (as you alluded to) doubts about her faith.

can you provide the options?

innocence can be defined as the lack of sin, relating it with the lack of guilt, also it can be a synonime of naivety. most people agree that sins are made out of experiences, intentionally or not, as well as you stop being naive once certain things happen to you throughout your life. so, with this explained, the chosen answers are:

when the boy saw the effects of war, he no longer viewed life as innocent.

the loss of innocence is a result of gaining experience and making mistakes.

one way to define innocence is as a lack of worldly experience or sophistication.
