It could be a metal.

Answer 1

The appropriate response is: It must be a metalloid.

Metalloids are elements that have properties intermediate between metals and nonmetals. They can be brittle and have semiconductive properties, which fits the description of your unknown material. Nonmetals, on the other hand, are typically not brittle solids and are not semiconductors in the same way metalloids are. Metals are usually malleable and ductile, which does not align with the "brittle" characteristic.
