According to the article,  why are metals not used  on transistors and  integrated circuits?

A. Metals can't be found very easily  in nature.

B. Metals are not malleable

C. Metals are too expensive

D. Metals are tough to control the  flow of electric current.

C. Metals are too expensive

Explanation:

Copper and other metals can be used as conductors, but they can "make it difficult to control an electric signal." Furthermore, when compared with silicon, which is "very inexpensive to produce," they are much more costly. Moreover, semiconductors, and especially silicon, can both conduct and insulate.
