Cases for electrically operated instruments are made of

Plastic
Aluminum
Iron or steel
Carbon fiber

The correct answer is: Iron or steel

Cases for electrically operated instruments are typically made of iron or steel due to their abilities to shield electronic components from electromagnetic interference and provide physical protection. Plastic and carbon fiber are not usually used for these cases because they may not provide adequate protection against electromagnetic interference and are not as durable as iron or steel. Aluminum is a lightweight material commonly used in aircraft construction but is not the most common choice for electrically operated instrument cases due to its lower magnetic shielding properties compared to iron or steel.
