The correct answer is (d) Compression, Tension, Shear

For explanation: Measurements of strength of molding sands carried out on the universal sand strength testing machine. The strength measured such as compression, shear and tension. The sands that could be tested are green sand, dry sand or core sand. The compression and shear test involve the standard cylindrical specimen that was used for the permeability test.
