(B) Sucrose

• Sucrose is the end product of photosynthesis and the primary sugar transported in the phloem of most plants.

(D) Lipids

• Lipids are a major component of biological membranes and are used as a compact energy source for seed germination.

Hence, option (C) is correct. Plants store carbohydrates in the form of starch.
