Alright, let's see... If R1 is the ASBR, then it should be generating the type 4 LSA. But the question says there are no stub networks, so I'm going with C.

Wait, why would R1 generate a type 4 LSA? Isn't it R3 that's the ASBR? This question is tripping me up.

I think the answer is C. Router R3 generates a type 4 LSA that is flooded to areas 0 and 2, since it is the ASBR and is responsible for advertising external routes to the other areas.
