What element do the potential solutions of raising the retirement age

I believe the question is incomplete, the complete question should have been: What element do the potential solutions of raising the retirement age, increasing payroll taxes, and reducing benefit payments all share?A.Each one would completely solve the Social Security problem. B.Each one would require someone to give up money and/or benefits.C.Each one would be protested by people who are already retired. D.Each one would force citizens to wait longer to collect benefits.

The correct answer is

B. Each one would require someone to give up money and/or benefits.

Explanation:

Raising the retirement age would make people to lose some of their benefits and entitlements because they will be getting their money some few years later than the normal time and they will have to work for more time since the initial retirement age has been increased

Increasing payroll taxes would cause the people to have more money deducted from their salaries meaning that they would be receiving less money for still the same job.

Reducing benefit payments would cause people who have different types of needs to receive lower money and have lesser resources to get the things they needed

In relation to this, the element which the potential solutions all share is that each one require someone to give up money and/or benefits and therefore, option B seems to be the correct answer
