In a crystal, there exist a point defect of the interstitial atom. If solute atom is larger than the solvent atom, then which is true for the edge dislocation?

In a crystal, there exist a point defect of the interstitial atom. If solute atom is larger than the solvent atom, then which is true for the edge dislocation? Correct Answer Compression side of edge dislocation will repeal and will be attracted to the tension side

If the solute atom is larger than the solvent, it will create a local region of compression. So the tension side of dislocation will attract at this region, and compression side will repel from this region.

Consider the following statements regarding crystal defects: 1. In metals, a self-interstitial introduces relatively large distortions in the surrounding lattice because the atom is substantially larger than the interstitial position in which it is situated. 2. All crystalline solids do not contain vacancies and, it is possible to create such a material that is free of these defects. 3. Impurity point defects are found in solid solutions, of which there are two types: Substitutional and interstitial.  Which of the above statements is/are correct?
