The correct answer is answer C ("In the 1980s").

The difference was made when IBM brought to the market the revolutionary concept of a Personal Computer (PC), which for the first time allowed a single user to operate a computer. Before then, the user would give commands to a mainframe computer and a whole team would have process the request and operate the machine in order to bring results.
