The question is based on the concepts of Subject-Verb agreement and Tense.
At first sight, the list of participles (grown, harvested, concentrated and frozen) might mislead us into looking at the question as a parallelism-based one. However, Option B is the only one that deviates from the pattern. So, that is one reason to eliminate B.
The other reason is Subject-Verb agreement. Option B has the plural verb ‘are’. The subject of the sentence is “Most citrus”. The first part of the sentence also contains the verbs ‘reaches’ and ‘comes’, which tell us that the subject is singular. Therefore, the plural verb ‘are’ is wrong in this sentence, since all the verbs refer to the subject ‘Most citrus’.
Option E can be eliminated for the same reason as Option B. It also has the plural pronoun ‘they’, which cannot be used to refer to the singular antecedent ‘Most citrus’.
We are left with Options A, C, and D.
The difference among the three options is of tense. Option A contains the verb ‘has been grown’ in the present perfect tense.
Option D contains the verb ‘was grown’ in the simple past tense.
Option C contains the verb ‘is grown’ in the simple present tense (passive).
Of the three, D can be eliminated as the verbs in the first part of the sentence are in the present tense and there isn’t a drastic difference in time in the sentence to justify a change in tense.
To maintain consistency of tense, the simple present tense should be used instead of the present perfect tense. Furthermore, the adjective ‘most’ indicates that a general statement is being made about ‘citrus’ and the verbs in the simple present tense corroborates that. The simple present tense is used to make general statements or convey universal truths.
Therefore, C is the best option.
