Energy is released when the third phosphate group breaks off.
Energy is produced when a fourth phosphate group binds to the molecule.
Energy is produced when the sugar ribose is metabolized in the Krebs cycle.
Energy is released when the adenine base is used to form part of an RNA molecule.

The correct statement regarding how ATP (adenosine triphosphate) is involved with the production of energy in a cell is:

Energy is released when the third phosphate group breaks off.

When a phosphate group is removed from ATP (converting it to ADP - adenosine diphosphate), energy is released, which can be used for various cellular processes.
