The internal (cellular) energy reserve in autotrophs is

(c) Starch [Plants store food in the form of starch]

Starch is a polymer of carbohydrate having a large number of glucose units which are joined by glycosidic bonds. Its basic chemical formula is (C6H10O5)n. This formula is similar to that of glucose,i.e. C6H12O6, where 'n' is the number of glucose molecules present. Two forms of starch: amylose, the branchless form, and amylopectin, the branched form pave the way for plants to store energy for their growth and development.
