Final Answer:
Among the provided options, the most common locations for finding dust buildup in a household are C) Headboards and E) Dusting lamps.
Step-by-step explanation:
Dust tends to accumulate on surfaces where air circulation is limited and where particles can settle. Headboards (option C) are often overlooked but can accumulate dust over time, especially in bedrooms where airflow might be restricted. Dusting lamps (option E) is also common as the tops and shades of lamps provide surfaces for dust to settle.
While bedside tables (option A), polishing doorknobs (option B), and cleaning ceiling fans (option D) are household chores, they may not necessarily be the primary areas where dust accumulates.
Bedside tables and doorknobs are frequently touched surfaces, but they may not accumulate as much dust compared to larger surfaces like headboards or lamps. Cleaning ceiling fans is essential, but the dust tends to be more visible on the blades rather than in the surrounding areas.
Regular dusting and cleaning of these common household items not only maintain a clean and pleasant living environment but also contribute to overall health by reducing allergens and improving air quality. Understanding where dust is likely to accumulate helps prioritize cleaning efforts for a more effective household cleaning routine.
