Given below are two statements: Statement I: The elastic potential energy per unit volume stored in a stretched wire is equal to \( \frac{1}{2} \times \text{stress} \times \text{strain} \). Statement II: Poisson's ratio is a dimensionless quantity whose value depends only on the nature of the material and typically lies between \( 0.28 \) and \( 0.30 \) for steels. In the light of the above statements, choose the most appropriate answer from the options given below:

1. A
   Both Statement I and Statement II are correct.
2. B
   Both Statement I and Statement II are incorrect.
3. C
   Statement I is correct but Statement II is incorrect.
4. D
   Statement I is incorrect but Statement II is correct.
