more about "two-year" low
the principal objection here is that the meaning is incorrect/unclear: for instance, a 'two-year low level' could mean that it hit a low level and then stayed there for two years.
we can see that this answer choice has (or at least primarily suggests) the incorrect meaning: a two-year low level would be a low level that lasted for two years. that's not the intended meaning in the problem.
