Stan: A fairly recent communications development allows people to use Internet connections as their phone lines at home. In the very near future, this form of land line will completely replace the existing telephone lines.
Heather: I think that even though fewer people may end up using the traditional land line setup, it will not be replaced completely anytime soon.
Which of the following, if true, most strengthens Heather's objection to Stan's claim?
A. Phone lines wired through Internet connections are generally much cheaper than those supplied by traditional telephone cable companies.:-

B. The home cellular phone lines have a better chance of replacing the traditional landline than the Internet phones.
Better chance can not guarantee that old line will get replaced or will stay C. Research has shown that when there is a dominant provider of communication services in any given area, a monopoly is formed, and other providers tend to be assimilated by that monopoly.
Correct, it will strengthen the Stan's claim D. Phone lines that are wired as Internet connections are less reliable than telephone cable lines, and can sometimes distort speech or disconnect.
Nothing is being mentioned about reliability E. Almost all of the current telephone devices have the capability of functioning with an Internet-based phone line.
This will not strengthen the claim
