Answer:
The correct answer is C. Although standards of living have fallen, polls still show the current government will win the next election.
Explanation:
The word although implies an expression by which a situation occurs that, despite the adverse antecedents, is generated in a surprising way.
Thus, for example, it shows that a result occurs despite not being sought: "although he did not train enough, the boxer won the fight".
Thus, this word functions grammatically as a breaking point between the antecedent and the result, clarifying that they are not logically linked.
