a
It is given off as heat.
When energy is conserved or transferred in a system, but some becomes unavailable to do useful work, this is often a manifestation of the second law of thermodynamics. The unavailable energy is typically converted into heat, which is dissipated into the environment. Heat is considered a less organized form of energy, and once it is dispersed into the surroundings, it cannot be fully converted back into useful work without adding more energy into the system. This process usually increases the overall entropy of the system and its surroundings.
