Answer:
B.Each one would require someone to give up money and/or benefits.
Step-by-step explanation:
Raising the retirement age would cause people to lose some benefit as they will be getting their money a few years later and they will have to work for more time.
Increasing payroll taxes would make people to have more money deducted from their salaries which means that they would be receiving less money for the same job.
Reducing benefit payments would make people with different types of needs to receive less money and have fewer resources to get the things they require.
According to this, the answer is that the element that the potential solutions all share is that each one require someone to give up money and/or benefits.
