Answer:
C) the potential energy of chemical bonds.
Step-by-step explanation:
Plants are autotroph i.e. they are the organisms which are capable of making their own food. The green leafs of plants have a specialized organelle named as chloroplast which is responsible for converting energy of sunlight into potential energy of chemical bonds by the process of photosynthesis. During the process of photosynthesis, the sunlight which is captured by plant leafs is utilized to convert carbon dioxide and water into glucose and oxygen. In short, the energy of the sunlight is stored in the form of chemical energy in the bonds of glucose. When this glucose is oxidized in an organism's body, this chemical energy which is stored in glucose is converted into any other form of energy like mechanical energy, kinetic energy etc.
