Right choice is (c) plastic anisotropy

The explanation: Lankford coefficient is a measure of the plastic anisotropy of rolled sheet metal. It is used as an indicator of the formability of recrystallized low-carbon steel sheets. It ensures near-identical behavior, irrespective of the orientation of the deformation in relation to the rolling direction, an important consideration in drawn and redrawn (DRD) can manufacture.
