Primary porosity refers to the space in sediment or rock that is created during its original deposition. Compaction of grains can reduce this primary porosity as the pressure of overlaying layers causes the grains to pack more closely together. Cementation of grains also reduces primary porosity as minerals precipitate and bind the grains together. Therefore, both A and B are correct as they can reduce primary porosity.
