Answer: B. Stupidity
Step-by-step explanation:
The question relates to the work of Friedrich Nietzche in his essay, "Morality as Anti-Nature".
In this essay he makes his disapproval of morality taught by Religion known as he posits that the fundamental thing wrong with morality is it's ties to Religion.
In paragraph 12, he speaks to how the Priest, a representation of the leadership of the church, has through his holy WITLESSNESS, has failed to be understanding and compassionate and as a result, they that are have found a way to utilize it ij their favor.
This infers that the Priest has been stupid to behave in the manner described meaning therefore that Witlessness here speaks to Stupidity.
