A decade after initiating the nation's most comprehensive and aggressive antismoking program, per capita consumption of cigarettes in California declined from over 125 packs annually per person to about 60, a drop more than twice as great as in the nation as a whole.










(A) per capita consumption of cigarettes in California declined from over 125 packs annually per person to about 60, a drop more than twice as great as





(B) annual per capita consumption of cigarettes in California declined from over 125 packs to about 60, more than twice as great as that





(C) California's annual per capita consumption of cigarettes declined from over 125 packs per person to about 60, more than twice as great as the drop





(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





(E) California has seen annual per capita consumption of cigarettes decline from over 125 packs per person to about 60, more than twice as great as that

排除法答案选D，但是不明白那个annaually放在那究竟修饰over 125 packs还是decline，按语法理解修饰125 packs讲不通啊（副词放在名词后能修饰名词吗？）如果修饰decline逻辑上翻译过来意思不对：prep语法笔记貌似就是这么理解的：人均吸烟量每年下降125到每年下降到60？完全不通！！
求解释，另求D项准确翻译
