Answer 1

Hint: A descendent of James Otis, a British foreigner who showed up in North America in the seventeenth century, Elisha Graves Otis was conceived in 1811.

Complete solution:
The skyscraper boom in U.S. cities was encouraged by Elisha Otis' advancement of the elevator.
He experienced childhood in Vermont prior to moving to the province of New York to fill in as an expert technician. Working for the Bergen Company in Yonkers, he introduced a "security raise" in a structure in 1852 as a way to forestall the unexpected fall of the lift. After five years, he planned and developed the primary security lift in a New York City building. By 1861, following extra upgrades to his framework, Otis' children shaped the Otis Elevator Company. Along with different advancements in building rehearsals, the lift turned into the foundation for the viable improvement of the high rise, the first rose in New York City. The lift accordingly changed the metropolitan scene and, thusly, the manner in which organizations worked in urban areas. His creation empowered structures and draftsmen's minds to climb ever upward, giving another and bolder shape to the advanced metropolitan horizon.
Simultaneously, the requirement for business space that followed the period of prosperity in North American urban communities during the 1870s implied that midtown areas were at a higher cost than expected. The presence of the iron-organized structure joined with the presence of the lift, freed the path for the appearance from the primary high rises since metal structures permitted superior dissemination of the structure's weight and could incorporate the deep openings without unduly focusing on the structure's interior structure.

Hence, the correct answer is option B.

Note:
The approach of the lift in structures turned around numerous patterns and made new ones. For example, inns that experienced issues filling upper levels currently found that they could accuse more for rooms of a view.
