Explanation

Electrostatic Discharge (ESD) can instantly damage sensitive computer components. The two best practices are: (A) Grounding yourself before touching components-using an anti-static wrist strap connected to a grounded surface dissipates any static charge built up on your body before it can arc to a component; and (D) Handling cards by their edges-the edges of PCBs are non-conductive; gripping a card by its edges avoids direct skin contact with integrated circuits (ICs), solder points, and traces where ESD could cause damage. Avoiding RFI sources (B) pertains to radio frequency interference, not ESD. Cool and dry conditions (C) are recommended to reduce static buildup but are environmental controls, not direct handling practices. Eye protection (E) protects against physical debris, not ESD. Plugging hardware into a grounded outlet (F) applies to powered equipment, not to the handling of components during installation.
