I think that it is d sedimentary because it is built up of layers of rock that can easily be chipped off. Igneous rock is formed from lava flows, either extrusive or intrusive. Metamorphic rock is made from old rock. Basalt is a type of igneous rock. By process of elimination, sedimentary seems to be the best answer. I hope this helps!
