The calculation involves understanding the current legal status of cousin marriage in each state. There are 50 states in the U.S., so "half of the states" implies that approximately 25 states permit marriage between first cousins. It's crucial to check the most recent legal information as state laws can change over time due to legislative actions or court decisions. Therefore, the answer provided here is based on the prevailing legal landscape as of my last knowledge update in January 2022.
It's noteworthy that cultural, religious, and legal perspectives on cousin marriage vary globally and within different regions. The United States reflects this diversity in its state-by-state approach to regulating cousin marriage. Individuals seeking up-to-date and precise information should consult the relevant state laws or legal resources for the most accurate and current details on this matter.
Therefore,the correct option is c. half of the states.
