The correct option is (b) The kinematics of bending deformation of thin bodies subjected to transverse loads
The explanation is: The term “plate” refers to solid bodies that are bounded by two parallel planes whose lateral dimensions are large compared with the separation between them (i.e., the thickness of the plate). In most cases, the thickness is no greater than one-tenth of the smallest in-plane dimension. Geometrically, plate problems are similar to the plane stress problems except that plates are also subjected to transverse loads. Thus, the simple two-dimensional plate theories account for the kinematics of bending deformation of thin bodies subjected to transverse loads.
