Who invented the telephone?

• A. Alexander Graham Bell
• B. Thomas Edison
• C. Wright Brothers
• D. Henry Ford

Answer: (A)

Recognize who first made a working device that could send human voice over a distance as electrical signals and then convert them back to sound. Alexander Graham Bell is credited with this breakthrough because he secured the first practical telephone patent in 1876 and demonstrated a device that could transmit clear speech over a distance. This achievement established the foundation for modern telecommunications. The other figures are known for different major inventions—Thomas Edison contributed to improvements in electrical devices and the phonograph, the Wright brothers invented the first powered airplane, and Henry Ford revolutionized automobile production—so they are not credited with inventing the telephone.
