The invention of microcomputers in the early 1980s led to a significant increase in computer use, as these smaller and more affordable machines became more widely accessible to individuals and businesses. While printers and networks were also important technological developments, they did not have the same transformative impact on computer use as the invention of microcomputers. Therefore, the best choice is C.
