Explanation:

The filament in an x - ray tube, similar to that in a light - bulb, is typically made of tungsten alloy due to its high melting point and ability to withstand high temperatures when heated to emit electrons. Silver - coated metals are not used for this purpose. A PYREX envelope is the glass housing around the filament, not the material of the filament itself. Radioactive elements are not used for the filament.

Answer:

C. tungsten alloy
