Plants are more efficient at acquiring carbon than are fungi, in the form of carbon dioxide, and converting it to energy-rich sugars.

　　(A) Plants are more efficient at acquiring carbon than are fungi,

　　(B) Plants are more efficient at acquiring carbon than fungi,

　　(C) Plants are more efficient than fungi at acquiring carbon,

　　(D) Plants, more efficient than fungi at acquiring carbon,

　　(E) Plants acquire carbon more efficiently than fungi,

答案说in the form of 修饰carbon，是不是所有介词短语都是修饰前面的名词，而不是主语？

如这句，By 1999, astronomers had discovered 17 nearby stars that are orbited by planets about the size of Jupite。about介词短语也是修饰planets.
