Answer: D. angular unconformity
Step-by-step explanation:
The unconformity can be define as a geological disturbance in which the buried erosional surface separates the two rock masses, indicating the fact that these sediments are not continuous.
In the case of angular unconformity the horizontal parallel strata or sediment rocks are deposited over a tilted and eroded layer form. This results in the production of the angular disordance along with the overlying layers which are horizontal.
