请教大全577跟准确率

1.        People who inherit the sickle cell anemia gene from only one parent seem to be resistant to malaria, an evolutionary advantage that may explain why a genetic condition so debilitating to many individuals has survived in the human population.

(A) seem to be resistant to malaria,

(B) seemingly are resistant to malaria,

(C) seem to be resistant to malaria and have

(D) seemingly are resistant to malaria and to have

(E) are, it seems, resistant to malaria, and they have

答案是A，可是我总觉得in A, an evolutionary advantage 好象在修饰malaria, 所以很想听听大家的意见。

最近拼命的练题和分析，可是准确率怎么也超过不了85%，也真希望能探索一下大家的经验。

从语法角度，我也觉得A指代的可以是句子，也可能是malaria，可是其他的都明确不对，只能选A了
