    A.however much it costs
    B.how much does it cost
    C.however does it cost much
    D.no matter how it costs

    答案：A
    解析：
    考查让步状语从旬。特殊疑问词+ever既可引导让步状语从句，也可引导名词性从句。本句中however引导的是一个让步状语从句，however后面要接形容词或副词，however much it costs相当于no matter how much it costs。句意为“我已经告诉你了，无论花多少钱，我都要买它”。故A项正确。
