Final answer:
The safest and most recommended option in this situation is 3) Buy a longer cord for the appliance. Multiple cords or inadequate ones can cause voltage drops, affecting the appliance's performance and posing safety risks.
Step-by-step explanation:
The safest and most recommended option in this situation is 3) Buy a longer cord for the appliance. Using extension cords, especially multiple ones daisy-chained together (as in option 4), can pose safety risks. Extension cords are designed for temporary use and should not be a permanent solution for reaching outlets. Option 1) Use one extension cord is acceptable if it's a temporary solution and the extension cord is in good condition, rated for the appliance's power requirements, and used properly. However, it's still preferable to have a cord of appropriate length. Option 2) Move the appliance closer to the wall outlet may be feasible in some situations but might not be practical or possible in all cases. It's essential to prioritize safety and convenience when addressing electrical setups in your living space.
