请教PREP 16

16.      (25451-!-item-!-188;#058&001942)

In her later poems, Phyllis Wheatley's blending of solar imagery, Judeo-Christian thought and figures, and the images she borrowed from ancient classicism suggesting her range and depth of influences, not the least of which is her African heritage.

(A) the images she borrowed from ancient classicism suggesting

(B) borrowing images from ancient classicism, suggests

(C) she borrowed images from ancient classicism, which suggests

(D) images borrowed from ancient classicism suggests

(E) images that she borrowed from ancient classicism, suggesting

我想问一下，为什么谓语动词是单数呢？我觉得主语是Phyllis Wheatley's blending of solar imagery and the images she borrowed from ancient classicism，所以谓语动词应该是suggest啊，谢谢大家。

看破解的注释，主语 blending
