In the photo above, what sort of rock is this?

a. metamorphic; the rock separated into layers as it was cooked and squeezed deep in a mountain range.
b. igneous; the layers were caused by flow processes during the eruption that released this.
c. marmot #2 sediment that isn’t rock yet. the layers are alternating silt and sand from deposition from landslides off the olympic peninsula into the trench offshore.
d. sedimentary; the layering was caused by changes in the flow velocity of the river that deposited the material
