At the end of 2001, motion picture industry representatives said that there were about a million copies of Hollywood movies available online and expected piracy to increase with high‐speed Internet connections that become more widely available.
(A) online and expected piracy to increase with high‐ speed Internet connections that become more widely available
(B) online and expect the increase of piracy with the wider availability of high‐speed Internet connections
(C) online, and they expect more piracy to increase with the wider availability of high‐speed Internet connections
(D) online, and that they expected the increase of piracy as high‐speed Internet connections would become more widely available
(E) online, and that they expected piracy to increase as high‐speed Internet connections became more widely available
D为什么不对，为什么expected 后面用would 就不可以？expected是过去式，后面的将来时用的也是过去将来时would啊， 不知道有什么问题，时态渣跪求大神讲解啊。。。

想了十分钟
个人意见~
As从句一般和主句在一个时态

这里我们去掉过去，用现在的眼光来看这个句子的话，D就变成了：
As Interent  WILL become more widely available, they expect the increase of piracy.

这俩不在一个时间点上呀~
而且从逻辑上来讲，这里as是原因状语从句，哪有原因在将来，结果在现在的呢~
