关于during的时态(PREP 80)

tasteofbit

关于时态部分总是有点糊涂，下面这个问题只是做完后想到的，请较大家一下

Radiocarbon dating of fossils taken from caves on islands along southeastern Alaska’s coast suggest that at least a portion of the area was remaining ice-free during the last ice age.
A. suggest that at least a portion of the area was remaining
B. suggest at least a portion of the area remaining
C. suggests that at least a portion of the area remained
D. suggests at least a portion of the area that had remained
E. suggests at least a portion of the area to have remained

 

答案是C，关于这点我没什么异议。只是突然想到during的时态问题。如果D选项改为"suggests that at least a portion of the area have remained"，那么这个答案是否也可以呢？

关于类似的问题，我也一直搞不懂

对解释：during要用过去时，也有疑义
白勇语法总结里，during+the last+时间短语     是判断使用现在完成时的时间标志
D，E应该错在后面，定语从句应尽可能简化，常省略that/which 和be动词
