B) phosphate
Explanation:
ATP is an organic molecule which is quite complex and primarily its function in the body is to provide energy. The full form of ATP is adenosine triphosphate. It is made up of a ribose sugar molecule, purine nitrogenous base and a string of phosphate groups. All the energy which lies in the ATP is in the bonds of inorganic phosphate groups. When the bond of phosphate group breaks large amount of energy is released which we use in our day to day activities like walking, running, sitting, sleeping etc.
