Haha, this question is a real head-scratcher! I'm going to go with C just to see what happens. Who knows, maybe the Viber account is actually the IMSI number itself!

I think D is the right answer. The ICCID, which is the unique identifier for the SIM card, should be the one that can be linked to the Viber account.

Looks like the correct answer is B. The Viber account can be tied to the user with the given IMSI number, which is the unique identifier for the SIM card.
