答案：B
解析：
词义辨析【直击答案】本题空格所在句为several factors work__6 the disappearance of the paper system.本句前是由although“尽管…”引导的让步状语从句，故从句和主句含义是转折关系，意为“尽管电子支付方式可能比纸币支付方式更有效率，然而以下因素阻止了纸币系统的消失”，故答案为B项against。work against…“妨碍，对……产生消极影响”。【命题思路】本题考查考生对让步状语从句的理解，同时考查同一动词搭配不同介词动词短语意义的辨析。【干扰排除】本题四个选项是动词work搭配不同介词的动词短语，有一定干扰性。D项干扰性较强。如考生没有理解although引导的让步状语从句的含义，便会误选D。
