Which Of The Following Igneous Rocks Has A Pyroclastic Texture

Which Of The Following Igneous Rocks Has A Pyroclastic Texture. A rock with a pyroclastic texture is termed a tuff if the largest fragments are less than 2.5 inches long, a volcanic breccia if the fragments are larger. The ash is very fine grained, so only the rock fragments and pumice are identifiable.
