Answer:
(D) California has seen per capita consumption of cigarettes decline from over 125 packs annually to about 60, a drop more than twice as great as that
Explanation:
There are several grammatical errors and repetition in the options A, B, C and E. Some of the errors include the use of "per capita consumption" and "per person". The two phrases literally mean the same thing. Furthermore, the sentence should start with a noun such as California. Therefore, it can be concluded that the right answer is option D.
