In the absence of any external stress, which one of the following statements related to the interaction of point defect and a dislocation is FALSE:

Your answerChoose one option.

An oversized solute atom would preferentially migrate below the slip plane of an edge dislocation.

A spherically symmetric point defect can interact with both the hydrostatic and shear stress fields of a dislocation.

A point defect can locally modify the elastic modulus and thereby can change the interaction energy.

Vacancies are attracted towards the compressive region of dislocation.
