+1 for C.

(A) increased dramatically over the past decade, while the number of drivers who report car accidents with deer on highways is more than four times what it was --> increased = Verb-Tense error, over the past decade = Unnecessary

(B) increased dramatically, while the number of drivers reporting car accidents with deer on highways is more than quadruple what it was at that time --> increased = Verb-Tense error

(C) has increased dramatically, while the number of drivers reporting car accidents with deer on highways has more than quadrupled --> Rectifies both Verb-Tense error and diction error

(D) has increased dramatically over the past decade, while the number of drivers reporting car accidents with deer on highways is more than four times what it was at that time --> over the past decade = Unnecessary

(E) has increased dramatically over the past decade, while the number of drivers who are reporting car accidents with deer on highways are more than quadruple what they once were --> over the past decade = Unnecessary

Hence, C.

(A) increased dramatically over the past decade, while the number of drivers who report car accidents with deer on highways is more than four times what it was:continuous action of past continuing in present requires has

(B) increased dramatically, while the number of drivers reporting car accidents with deer on highways is more than quadruple : continuous action of past continuing in present requires has

(C) has increased dramatically, while the number of drivers reporting car accidents with deer on highways has more than quadrupled

(D) has increased dramatically over the past decade, while the number of drivers reporting car accidents with deer on highways is more than four times what it was at that time: redundant with over last 10 years

(E) has increased dramatically over the past decade, while the number of drivers who are reporting car accidents with deer on highways are more than quadruple what they once were : redundant over last 10 years

A, D and E are out as "over the past decade" is redundant.

B is wrong because of two reasons:
1) Verb tense error
2) Unnecessary Wordy

MANHATTAN REVIEW OFFICIAL EXPLANATION:



The phrase ‘over the past decade’ is repetitive, as the beginning of the sentence refers to the last ten years. Eliminate A, D and E. The population has increased over a period of time in the past. That period started in the past and continues up to the present. Therefore the present perfect tense should be used. Eliminate B. Choice C is the correct answer.
