Q1: ESD would cause the most damage to which component?

ANS:B - Expansion board

Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.

A buildup of static electricity can be caused by tribocharging or by electrostatic induction.

The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.
