What I know of Sister Mary Joseph is from a disease. It is a nodule. Anyway, according to context, the best answer would be letter C. The word that best describes Sister Mary Joseph is Spiritual. This is because of the amount of biblical reference from the names.
C because it's following a noun
The answer is B/ inverted the subject verb order. There was a prepositional phrase in the first place, the sentence length is the same, and it did not create a compound sentence. <span />
Character vs. self I think, but it could be character vs. others.
