Aging in place refers to designing a home to allow individuals to live independently as they age, accommodating potential mobility and accessibility challenges. Flush thresholds eliminate tripping hazards, grab bars provide support in areas like bathrooms, and lever handles are easier to operate for those with reduced hand strength or dexterity—key features for aging in place. Option B includes an ADA-height water closet and walk-in shower, which are beneficial, but the 30" clear door width is insufficient (ADA requires 32" minimum). Option C focuses on low maintenance but lacks critical accessibility features like flush thresholds. Option D includes wheelchair clearance and hardwood flooring, but ADA-approved wall sconces are not a primary concern for aging in place.
