To provide the best support for the answer to Part A, I would need to know what Part A specifically asks or what conclusion it leads to. However, if Part A discusses a negative perception of someone's character or actions, options A ("mean-spiritedness") and B ("no sense of decency") would likely be most relevant. If Part A pertains to a reaction or feeling of frustration, then C ("Fed up") could be applicable. Option D ("censured him") might relate to a formal reprimand but is less likely to directly convey a negative perception of character.
If you provide the context or the conclusion of Part A, I can help determine which quote best supports it.
