THE CORRECT ANSWER IS D. THE SUBJECT OF THE ORIGINAL SENTENCE IS &#...

2. The correct answer is D.

The subject of the original sentence is "the mountain cornfloss,"

which is singular. However, the main verb is "grow," which is

plural. We need to replace "grow" with "grows". Moreover, "thought

of as being" is wordy and awkward. We need to find a more elegant

way to phrase this.

Choice D corrects the subject-verb issue and also finds a more

economical phrasing in "and thought to be".
