Historian: "When the Computer Was First Invented, Most People Involved

Historian: "When the computer was first invented, most people involved never imagined that computers could become as small as they are today, and certainly never imagined that each person would own one or more computers. They were intended mainly as a tool for universities and governments and were incredibly expensive. Given the rapid progress in computer technology in recent decades, it is likely that it is hard to predict even today how computer technology will develop and what new uses we will find for computers."
Which of the following is most strongly supported by the historians statements?

A) Computers will develop in a way that we find impossible to predict today.
B) When computers were first developed, they were not intended as personal devices.
C) Computers are more appropriate for universities and governments than individual users.
D) Looking at the history of computers makes it clear that it's hard to predict the future development of the field.
E) Early developers of computers were naïve in assuming that computers would not advance as much as they have.
