Choice C – This choice has verb tense error. Element 2 uses past perfect tense. Whenever past perfect tense is used, there should be a related event in simple past tense to indicate the intended sequencing of event. In this sentence there is no such event and hence use of past perfect tense is incorrect. Furthermore, this choice appears to be wordy. Two relative pronouns referring to same noun – growth seems wordy.
