Correct Answer:
B. Elias Howe
Elias Howe is widely credited with inventing the first practical sewing machine in 1846. His machine featured a needle with an eye at the point and a shuttle operating beneath the cloth, creating a lockstitch, which was a significant improvement over previous designs.
- Thomas Saint (A) patented a design for a sewing machine in 1790, but it was likely never built or practical.
- Isaac Singer (C) made significant improvements and commercialized the sewing machine, but did not invent the first practical one.
- George Stephenson (D) was a pioneer of railways and steam locomotives, unrelated to sewing machines.
