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
题目分析：原文存在一个比较，就是plants和fungi在获得carbon这个方面的比较，A凑合，B than后面没有are与前面的plants are 无法形成对比，干掉。C说凑合 D连谓语都没有，干掉。E than后面什么都没有，可是前面有动词acquire，如果than后面加does还凑合。C显然比A在意思一致的情况下一气呵成，简洁一些，选C
