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

1. Plants are more efficient at acquiring carbon than are fungi

2. Plants are more efficient at acquiring carbon than are fungi

3. Plants are more efficient than fungi at acquiring carbon

4. Plants, more efficient than fungi at acquiring carbon

5. Plants acquire carbon more efficiently than fungi

 答案是C,我选A,为什么 不对啊

Plants are more efficient than fungi at acquiring carbon, in the form of carbon dioxide(carbon的补语) , and converting（与acquiring并列，这里应该补出介词at会更清晰） it to energy-rich sugars.
            

所以A的修饰关系不正确， in the form of carbon dioxide跟在了fungi后面。
