D creates a sentence fragment. It uses "more efficient than fungi at acquiring carbon" as a modifying phrase describing the subject (plants). The rest of the sentence, which is not underlined, continues with another modifying phrase ("in the form of carbon dioxide"). If we slash and burn them, we're left with a sentence of "Plants, and converting it to energy-rich sugars." We don't have a verb to go with our subject.

Hide the red part of the question and you can find the flaw in D.

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 and converting it to energy-rich sugars
D. Plants, more efficient than fungi at acquiring carbon and converting it to energy-rich sugars
E. Plants acquire carbon more efficiently than fungi

IMO: C
