The correct answer is B. Electrical shock. Electrical grounding provides a safe low-resistance path for fault current to flow to earth, protecting users from electrical shock if a device malfunctions or a live conductor contacts the equipment chassis.

Why each option
Electrical grounding provides a safe low-resistance path for fault current to flow to earth, protecting users from electrical shock if a device malfunctions or a live conductor contacts the equipment chassis.
Grounding addresses electrical hazards and has no effect on logical or physical security breaches such as unauthorized data access.
Proper equipment grounding ensures that if a fault causes a live wire to contact the metal chassis of a device, the excess current flows safely to ground rather than through a person touching the equipment. This prevents potentially lethal electric shock and is a foundational principle of electrical safety per NEC standards.
Chemical burns result from exposure to corrosive substances, which grounding does not mitigate in any way.
Equipment theft is a physical security concern addressed by locks or surveillance, not grounding.
