Answer»

The correct answer is (d) VLR, HLR

For explanation I would SAY: The visited system creates a VLR record for each NEW roamer and notifies the home system via IS-41 so it can update its own HLR. IS-41 allows the MSCS of neighboring SYSTEMS to automatically HANDLE the registration and location validation of roamers so that users no longer need to manually register as they travel.
