The placement of only allows the sentence to correctly express the thought that cultivated sunflowers rank second as a source of vegetable oil, with soybeans alone ranking first. B.The placement of only creates an ambiguity: does it modify soybeans or the phrase as a source of vegetable oil? In the latter case, the sense would be that being a source of vegetable oil is the only respect in which soybeans are more important than sunflower seeds. However, this does not seem to be the intended sense of the given sentence. The phrase in importance is unnecessary and would make the sentence wordy. C.The word being and the phrase in importance are unnecessary and make the sentence wordy. D.The phrase only second to soybeans appears to minimize the importance, initially suggested, of sunflowers’ being second to soybeans as a source of vegetable oil.

In either case it fails to capture the sense of the given sentence.
