Explanation:

FASTag have been made mandatory for all vehicles from December 2019.

Any vehicle, private or commercial, which has the FASTag will be able to swiftly make contactless payments at toll plazas on national highways.

FASTags are part of the National Electronic Toll Collection (NETC) program developed by the National Payments Corporation of India (NPCI).
A FASTag is essentially a tag that you attach to the windshield of your car, from the inside. This is Radiofrequency Identification (RFID) enabled and is linked with the registration details of your vehicle. Hence, option (a) is correct.
RFID is the wireless communication standard that reads the data that is encoded in tags or labels, by a reader device specifically made for that purpose.
