The correct answer is **A. It will possess an identical total energy right before impact as it did at the moment of release.**
This illustrates the conservation of energy principle because, in the absence of external forces like air resistance or friction, the total mechanical energy (potential energy and kinetic energy) of the arrow remains constant. When the arrow is drawn back in the bow, potential energy is stored, and when released, that potential energy is converted to kinetic energy as it travels toward the target. Right before impact, the total energy of the arrow is effectively the same as when it was released.
