Answer:

d. all of these types of clasts

Explanation:

  • As the clastic rocks type are all made of weathering and erosion of the rocks due to the mineral content changes in due course of time by the impact of the winds and water in action.  
  • The impacts the erosion and abrasion have on the sedimentary ricks are examples of sandstone and mudstone which have a certain level of angular grains that are eroded by the operating forces and the shapes are thus made out of the weathered geomaterials.
  • Being constructed by the rock fragments and sealed by the silicate minerals these rocks are thus a product of the weathered forces.
