Solution

Answer

The answer is D. It connected four sites at first.

Explanation

Option A: Its strength was its single, secure pathway.

This statement is incorrect. ARPANET's strength was not a single, secure pathway but rather its decentralized design, which allowed for multiple pathways and increased resilience against failures.

Option B: It took 20 years to develop.

This statement is incorrect. ARPANET was developed relatively quickly. The project began in the late 1960s, and the first successful message was sent in 1969.

Option C: It was developed by the Department of Education.

This statement is incorrect. ARPANET was developed by the Advanced Research Projects Agency (ARPA), which is part of the Department of Defense, not the Department of Education.

Option D: It connected four sites at first.

This statement is correct. ARPANET initially connected four sites: the University of California, Los Angeles (UCLA); the Stanford Research Institute (SRI); the University of California, Santa Barbara (UCSB); and the University of Utah.
