Explanation:

- Understanding Energy in Stretched Wire:

- When a wire is stretched, the work done to deform it is stored within the material.

- This stored energy is not in motion but is "locked" into the material's deformation.

- Energy Form Analysis:

- Option 1 - Kinetic energy: Involves energy due to motion, not applicable here.

- Option 2 - Potential energy: Correct, as the work done in stretching the wire is stored as potential energy due to the elastic deformation.

- Option 3 - Heat energy: Incorrect, as heat is not the primary form of energy in an unstretched wire.

- Option 4 - Electrical energy: Incorrect; stretching a wire does not convert mechanical work directly into electrical energy.

- The correct answer is Potential energy from Option 2.
