The energy is transferred into Heat and Elastic Potential energy. That means none of these have a 100% transformation only to them. Some is transferred to Heat which is literally the Heat Loss and maximum is transformed to elastic potential energy.
For interested mechanics geek, The wire with initial length, L , cross section, A , Young's modulus, Y and stretched with a length, l has an Elastic Potential energy, E = 2 1 L A Y l 2
Actually all of the options are correct but together, not individually!
