Concept / Timeline
Elisha Otis famously demonstrated his safety elevator in 1853. The first passenger elevator installation entered service in the Haughwout Building, New York City, in 1857 — generally cited in GK as the first elevator "built" for regular use.

Option analysis
1857 — Correct for first installed passenger elevator in regular service. 1853 — Public safety demonstration year, not the first installed passenger lift. 1880/1903 — Later advances (e.g., electric elevators), not the first installation.

Final Answer
