关于时态的考点

IWANT750

The results of the company’s cost- cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.
A. which increased five percent during the first three months of this year after it fell
B. which had increased five percent during the first three months of this year after it had fallen
C. which have increased five percent during the first three months of this year after falling
D. with a five percent increase during the first three months of this year after falling
E. with a five percent increase during the first three months of this year after having fallen
答案选C哈。
OG官方解释说是正确答案能表示出两件事前后的发生顺序，AB不能因为时态都一样。
但是我不知道C的after falling怎么就能表示出在have increased 之前呢？

但是A也有after啊，而且还用了过去时

A 错应该是错在it, 没有referent. Profits是复数.

凭借after引领的从句，已经可以得知increase的动作是发生在fall的动作之后
