Even though it was not illegal for the bank to share its customers' personal and financial information with an outside marketing company in return for a commission on sales, the state's attorney general accused the bank of engaging in deceptive business practices by failing to honor its promise to its customers to keep records private.
(A) by failing to honor its promise to its customers to keep
(B) by its failure of honoring its promise to its customers to keep
(C) in its failing to honor its promise to its customers of keeping
(D) because of its failure in honoring its promise to its customers in keeping
(E) because of its failure to honor its promise to its customers of keeping
这题答案是A，结果我做题的时候看到A就把它给排除了，本人一直认为 by failing ..... 修饰有歧义，完全可以理解为 accused the bank .... by .... 这样的话就是A选项就有错误修饰 accused 的嫌疑了呀 为什么A是对的呢？
