Answer: (C)

Verified step by step guidance

1. Identify the main topic of the question, which is controversies around social security.
2. Recall that social security primarily deals with the distribution of benefits, especially related to age groups such as retirees and working-age individuals.
3. Evaluate each option to see which one directly relates to social security: international trade deficits and military defense spending are unrelated to social security.
4. Recognize that the question about how benefits should be distributed among different age groups directly addresses social security concerns.
5. Confirm that the question about private firms setting minimum wage rates is related to labor markets, not social security.
