Solution
The torsional deformation of a shaft refers to option a. Twist of cross-section about centroid. This occurs when a torque or twisting moment is applied to the shaft, causing it to rotate about its axis. The cross-sections of the shaft, which were originally planar, remain planar after the torque is applied but rotate about the centroid or geometric center of the shaft. This rotation or twist is the torsional deformation.
