Correct Answer: Option 4 – Erosion of the igneous rock exposed at the surface

Since the sediment layers are formed due to continual deposition process, an event such as erosion that occurred most recently leads to formation of rock exposed at the surface. The diagram above shows the exposed part of igneous rock undergoing erosion. Hence, option 4 is the correct answer.

Layer A is in the lower part of the section. Hence, it is an older layer and option 1 is incorrect.

Formation of layer D falls next only to the erosion of the exposed igneous rock layer. Hence, it is not the most recent event and option 2 is incorrect.

There is no information on the tilting of all 4 sedimentary rock layers. Hence, option 3 is incorrect
