Answer is Wrong!
The answer is A. Tellurium.
Tellurium is a metalloid, while the other three elements are metals.
Metalloids are elements that have properties of both metals and nonmetals. They are typically brittle and poor conductors of electricity, but they can also be shiny and have a metallic luster.
Metals are elements that are typically shiny, good conductors of electricity, and ductile (can be drawn into wires).
Nonmetals are elements that are typically dull, poor conductors of electricity, and brittle.
