I will update the question. (This problem is a part of a larger problem and I forgot the conditions that I'd used.)

Even though both answers are correct, I'm going to mark this answer because it gives me a bit of intuition about what's going. The other answer would have been a better solution to an exam question.

I think you only need relative complement of included sets? I.e., $A \subseteq B \Rightarrow B \setminus A \in L$.

comment Example where union of increasing sigma algebras is not a sigma algebra
Not to me :) But, even if I were one of your students, I don't think this question goes beyond what students would discuss between themselves.
