Antiviral Agents Used to Treat Hepatitis B Virus Infection

You answered:

B Telbivudine (Tyzeka) and lamivudine (Epivir-HBV) are both L-nucleoside analogues that share cross-resistance.

This answer is correct. Telbivudine and lamivudine are similar in their mechanism of action and resistance patterns. Indeed, telbivudine cross-resistance is observed (in vitro) with all major lamivudine resistance mutations.
