Answer

Brief Explanations:

Electrostatic discharge (ESD) can damage sensitive electronic components. Working with normally - encased computer parts exposes them to ESD risks. Touching an unpainted metal surface (A) is less risky as it's not directly related to sensitive components. Unscrewing a laptop casing (B) is a start but not as risky as directly handling internal parts. Opening a desktop casing after power - off (C) is also not as risky as handling the internal parts. Handling normally encased computer parts (D) exposes them to ESD, which can cause damage.

Answer:

D. when you work with computer parts that are normally encased
