A perfect rigidity body means no matter how much load you apply to it is neither going to deform nor any shape change, The kinematics and dynamics study inherently says that body is perfectly rigid and no amount of force is going to change it's shape.
A rigid body is one manifesting a zero strain regardless of applied stress. Young modulus is defined as stress divided by strain, For a rigid material then young modulus is infinite.
Bulk modulus too is always given by volumetric strain and for the same reason above it will also be infinite.
