(b) Always cheaper than leased lines

(c) Usually cheaper than leased lines

(d) Usually more expensive than leased lines

This question was posed to me in an international level competition.

Asked question is from Virtual Private Networks topic in division Application Layer of Computer Network

Answer 1

The correct answer is (c) Usually cheaper than leased lines

Easy explanation: The services of a VPN are cheaper for moderate to large scale institutional networks than the services of leased lines. Though for a small scale network, it does not prove to be as beneficial as the costs are not reduced to a great degree as compared to leased lines.
