TVS diodes configuration for AC differential signal
The C configuration is correct because it presents bidirectional diodes, assuming that your circuit supports and/or uses negative voltage.
Note that all in one packages like the TPDE007 are better than discrete components because they are build for this purpose.
The resistors must be located as in configuration A. You still can add resistors to protect the TVS diodes as in D, but on top of those already in A. But bear in mind that each resistor will distord the signal. If it's a low frequency signal, it's OK.
Also don't forget that this resistor set up should or could be present at both trancievers. Which makes not two but four resistors between the two deivces.
More explanations in the datasheets, application notes and guidelines from manufacturers. Worth reading them. Read datasheets for other similar TVS diodes and you will get more informations.
