None of the above, actually. Pyrite is a mineral. Minerals are naturally occurring, inorganic substances. They have a distinctive chemical composition (Pyrite is iron sulfide), a crystalline structure (pyrite can form cubes, although is more often found as an irregular lump), and have distinctive physical properties (such as pyrite's metallic luster, which is why people mistake it for gold). Minerals are what comprise igneous, sedimentary and metamorphic rocks. Pyrite is a mineral, so it is neither igneous, sedimentary, nor metamorphic.
Pyrite could be found in any of the three rock types (sedimentary, igneous, metamorphic).

Iron pyrite, also known as fools gold, is mainly found in sedimentary rocks. It forms as a result of sedimentation and diagenesis processes.
