[求助]急！长久以来的困惑-predict, indicate后面到底能否跟would???

RT，想知道predict和indicate的过去时+从句+would这样的结构到底有没有错？之前看讨论帖说GMAT里predict后面不能跟would,但今天做GWD发现GWD-24-Q 23的答案是A...困惑ing...

Discussion of greenhouse effects has usually focused on whether the
                    Earth would warm and by how much, but climatologists have indicated all
                    along that the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation,
                        and storminess.

A.      the most obvious effects, and those that would have the largest
                    impact on people, would be extremes of temperature,
                    precipitation, and storminess

B.      the effects that are the most obvious ones, extremes of temperature, precipitation, and storminess, would be those impacting
                    the most on people

C.      those effects to have the largest impact on people, extremes of
                    temperature, precipitation, and storminess, are what are the most obvious effects

D.      extremes of temperature, precipitation, and storminess, the most
                    obvious effects, that they would have the largest impact on people

E.       extremes of temperature, precipitation, and storminess, which are
                    the most obvious effects, are those to impact the most on people
