The main purpose of grounding and bonding in electrical systems is to prevent electrical shock and reduce fire risk. Grounding involves connecting the electrical system to the ground, which helps to safely dissipate excess electrical energy into the earth in the event of a fault, thereby minimizing the risk of electrocution. Bonding ensures that all electrical parts and systems are connected together, eliminating potential differences in voltage that could cause a shock hazard. By creating a safe path for electricity to flow, grounding and bonding protect both people and property from potential electrical hazards, making this the correct answer.

The other options, while they touch on aspects of electrical systems, do not capture the primary safety focus of grounding and bonding. Enhancing efficiency or improving performance may be secondary benefits, but they do not address the critical safety concerns that grounding and bonding are specifically designed to mitigate. Lowering electrical bills is unrelated to the function of grounding and bonding, as these practices focus on safety rather than cost reduction.
