i am afraid we can't have coffee there's ___left.A,none B.nothingC.noD.no one

nothing仅对物而言，none可对任何事或人，例如，有人问Is there any people(books) in ... 应回答no one(nothing),Is there anything in... 可回答none . How do you do?这种问候人的句子中应回答nothing,What 的句子中依照上述情况选用nothing or none 选B是因为上文中已经说到是cake了，如果没说出来是什么东西就要用nothing
