John Roebling, the designer of the Brooklyn Bridge, was a civil engineer who invented twisted wire-rope cable.

Answer: Option A

<u>Explanation:</u>

Jhon Roebling, born on 1806 was a German immigrant who migrated to the united states around 1830. When he was hired to develop a canal system for Pennsylvania, he could see the hemp ropes which they used to pull up the barges were not strong enough.

He then started to venture the ideas to make strong as well as flexible ropes by twisting and winding together several steel wires. He then patented his invention in 1842.

He was the creator of the first wire suspension bridge between 1844 & 1845. Jhon Roebling founded a company of manufacturing wire cables in Trenton, New jersey. He flourished and continued his journey of constructing various structures and died in 1869.
