    Answer : Option A

    Explanation :

    Joseph F. Glidden was born in New York on Jan. 18, 1812. He invented barbed wire in 1873 and was granted the patent on Nov. 24, 1874. After a three year battle over the patent, which he eventually won, Gidden became known as the "Father of Barbed Wire".
