                                                      | A) Stratification | B) Windstorms | 
| C) Glacial Ice | D) Stream water | 
                              Answer:   A) Stratification

                           Explanation:
Stratification as actually the settling down of sediments with different properties to form layers/strata over years. Stratification especially occurs on the bed of water bodies such as oceans.
Stratified sedimentary rocks are used to study the ecological conditions over previous years/eras.
The other choices like Windstorms, Glacial Ice and Stream water are mediums which sediments are transported.
