In what year did Alexander Graham Bell receive a patent for the invention of the telephone?

Alexander Graham Bell received a patent for the invention of the telephone in 1876. This was a pivotal moment in the history of communication technology, as it marked the first successful attempt to transmit vocal sounds over telegraph wires. Bell's work led to significant advances in telephony and transformed how people communicate.

The year 1876 is significant because it was not just the year Bell received the patent but also the time when he conducted public demonstrations of his invention, effectively launching the telephone as a practical device. This innovation laid the foundation for modern telecommunications, and the patent he obtained was crucial in establishing his claim to the invention amidst competing claims from contemporaries.

Other years mentioned in the options represent either the development period of early telecommunication concepts or later advancements but do not align with the crucial moment of patenting the telephone itself in 1876.
