A. Yes the transmission is much faster as the speech is converted into light signals and send over fiber optic cables...and not like in the old technology wherein they modulated your speech with higher frequencies which in turn was transmitted over open wires.
B. Yes It is less expensive in the long run as the equipment is much more reliable and thus not so many faults on it...
C. No , analogue lines can also carry data from one modem to another..
D.NO .. Wireless transmissions are more for the rural areas where you don't have Fiber optics and Digital Exchanges...and can even be used for 30 km
Another big factor is the availability of spars for the older systems.. if you have a system that was designed in the 1960 (Mk6) ...you will struggle to get spares for it now...

If your question was multiple choice, I would choose (c). Some phone companies are getting the Cable TV business to go with their land-line, wireless(mobile) & internet. They need to compete. That cable they are putting in , I bet it's fiber-optic to handle the Hi-Def demands these days.

Not to mention the equipment that supports the analog lines take up a whole lot more room.
