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
那个after 是个介词  后面不可能接完整的句子的 所以a b 错 还有就是感觉那个 during the first three months of this year  是一个现在完成时的时间标志词 具体可以看一下白勇的书
