• B. Gold
• C. Silver
• D. Wood

Answer 1

The correct option is A

Silicon

Explanation for the correct option:

In the case of option A,

1. The semiconductor is a material that has electrical conductivity between the conductor and the insulator.
2. Silicon is a semiconductor.

Explanation for the incorrect options:

1. Gold and silver are metals.
2. In the case of option B, gold is used as a contact metal in the electronics industry because it is a good electrical conductor.
3. In the case of option C, the best conductor is silver. Electrons move freely in the conductor.
4. In the case of option D, wood is an insulator.

Hence, option (A) is correct.
