Which one of the following is a metalloid?

Germanium is a metalloid, exhibiting properties intermediate between metals and non-metals. Metalloids typically have a metallic appearance but are brittle like non-metals and are semiconductors. Common metalloids include Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium. Coke is a form of carbon (a non-metal), Iodine is a non-metal (halogen), and Sugar is an organic compound, not an element. Germanium is widely used in semiconductor devices, fiber optics, and infrared optics due to its semiconducting properties.
