为什么是A啊 请问各位！！！

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
(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

因为A没有its，by修饰engaging。如果有its，则会出现指代不清，attorney 或者 bank

A明明有its啊  还有两个its呢  两个

by doing 结构和because结构都是表因果关系的，in 不能表示这个逻辑关系,排除C
failure是抽象名词，抽象名词优先有动词
且by dong 结构优与because of 结构，becauese of 加较短的名词短语，否则会破坏句子结构

its promise to its customers这里的its应该是指bank
its failure应该是对的（至少在逻辑上，可以指代bank）

accused the bank of engaging in deceptive business practices 后面

跟着的就要说明是如何欺骗，而不是要说什么原因。所以用 because 就很不妥
