Alexander Graham Bell is credited with inventing what?

• A. The telephone.
• B. The phonograph.
• C. The light bulb.
• D. The mechanical reaper.

Answer: (A)

The question checks your knowledge of which famous invention is linked to Alexander Graham Bell and how it changed society. Bell is credited with the invention of the telephone, the device that lets people speak to one another over long distances by turning sound into electrical signals and back again. He and his team demonstrated and received a patent for a practical telephone in 1876, which sparked the growth of telephone networks and transformed everyday life, business, and government communication.

Other options refer to different inventors and uses: the phonograph records and reproduces sound, the light bulb provides electric illumination, and the mechanical reaper helps harvest crops. These are not Bell’s invention, but they illustrate how other innovations also reshaped society.
