Answer: The correct answer is scientist Robert Kahn and Vint Cerf in a project funded by the US Department of Defense.
Explanation: The first workable prototype of the Internet was developed by Robert Kahn and Vint Cerf in the late 1960s with the development of ARPANET, or the Advanced Research Projects Agency Network. This project used packet switching to allow multiple computers to communicate on a single network and was originally funded by the US Department of Defense.
The technology continued to grow in the 1970s after scientists developed Transmission Control Protocol and Internet Protocol, or TCP/IP, which is a communications model that set standards for how data could be transmitted between multiple networks. This was followed in 1990 by the invention of the World Wide Web by Tim Berners-Lee. This is the most common way for people to access the information that is on the internet.
