Answer
Answer : (d)
Explanation
Explanation : As surprising as its age is, the Internet was born from the U.S. military’s need to construct a decentralized computer network that could withstand a nuclear war. The network was used and refined by universities throughout the 1970s and 1980s, but it wasn’t until 1992 that the Internet was made available to the general public.
