Final answer:
All electrical outlets in residential bedrooms should be protected by tamper-resistant receptacles to reduce the risk of electrical shock.
Step-by-step explanation:
The correct answer is d. tamper-resistant receptacles.
All electrical outlets in residential bedrooms should be protected by tamper-resistant receptacles. These receptacles have built-in safety features that prevent children from inserting objects into them, reducing the risk of electrical shock.
Ground fault circuit interrupters (GFCIs), arc fault interrupters (AFIs), and surge protectors are also important safety devices in electrical systems, but they serve different purposes and are not specifically required for residential bedrooms.
