Right choice is (d) restrained temperature, external loads and frost action

Easiest explanation: The factors affecting stresses in rigid pavements are broadly placed in four categories:

Stresses due to restrained temperature and moisture deformation

 Stresses due to external loads

 Stresses due to volume changes of supporting material and frost action

 Stresses due to continuity of sub-grade support.
