Answer:
The correct answer is Sancho Panza reproaches the priest for his behavior and distrusts the priest's rectitude.
Step-by-step explanation:
Sancho Panza reproaches the priest's behavior, even implying that he knows him and that he knows that he is hiding something by telling him that he is disguising his lies.
Also, Sancho Panza is outraged by how the priest represents an obstacle for Don Quixote in his exploits and his attempts to help the most defenseless.
That is what Sancho Panza reproaches the priest.
