The answer to your question is OPTION D
This is a predicate adjective, as it immediately follows a copulative (=linking) verb "to grow". If it said - The tall grass, then "tall" would be nominative. This way it isn't, it is a predicative adjective.
The correct answer is D, because that is the only appropriate shift in tense. A isn't correct because present perfect tense (have raced) is used inappropriately, when it should have been past perfect. B is also incorrect because past perfect means that that action happened before the storm blew, which is not the case. C features future continuous tense, which is impossible due to shift in tense. Therefore, the answer is D, because there is an appropriate tense in that sentence, past simple.
