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:
A
An oversized solute atom would preferentially migrate below the slip plane of an edge dislocation.
B
A spherically symmetric point defect can interact with both the hydrostatic and shear stress fields of a dislocation.
C
A point defect can locally modify the elastic modulus and thereby can change the interaction energy.
D
Vacancies are attracted towards the compressive region of dislocation.

Correct : b
