Britain's first escalator was installed in Harrods in 1878.
B
Correct answer
Explanation
The first escalator was indeed installed at Harrods department store in London, but the date is WRONG. It was installed in November 1898, not 1878. The escalator was made by the Otis Elevator Company and was a novelty attraction - people were so nervous about it that Harrods stationed employees at the top with smelling salts to help frightened shoppers. The 20-year discrepancy makes the statement false.
