Ans.(c)
Autotrophs can convert CO2 and H2O into carbohydrates only in the presence of sunlight. Autotrophs have chlorophyll which takes sunlight and breaks water into hydrogen and oxygen and converts CO2  into carbohydrates but happens only in the presence of sunlight.

So statement (c) is incorrect and thus it is the right answer.
