Which of the following represents the greatest exposure to the integrity of electronic funds transfer data transmitted from a remote terminal?

A. Poor physical access controls over the data center
B. Network virus
C. Poor system documentation
D. Leased telephone circuits

I thought A B C are all okay answers, why D is prioritized over the other 3?

It is because the telephone circuits are public. This leads to a direct risk of exposure to data breaches. The other choices would be secondary risks of exposure.
