The correct answer is B) The telephone allowed for voice communication over a distance.

The telegraph was a telecommunication technology that used Morse code in order to deliver a message through telegraph lines that converted the code into electric signals. The telephone was invented in the mid-19th century and it was a technology that converted sound waves into electric signals that were transmitted through cables and then received by a receptor, which decoded the electronic message again into sound. For the first time in History, this technology allowed for direct voice communication between two users that were very distant from one another.
