Which type of prisoners must be separated according to correction law?

The correct answer focuses on the separation of husband and wife in correctional facilities based on correction law. In many jurisdictions, including New York City, the law often mandates that certain categories of prisoners must be kept apart to prevent conflicts and maintain order within the facility. Separating husband and wife serves multiple purposes: it helps to prevent potential manipulation, reduces the risk of collusion or disruptive behavior, and ensures that the integrity of the correctional environment is maintained.

In contrast, sibling pairs, common-law partners, and cousins do not typically fall under the same legal requirements for separation as spouses do. While relationships among inmates may warrant consideration in terms of proximity and potential issues, the legal obligation to separate is specifically emphasized for married couples. This is because the dynamics of a spousal relationship can be considerably more complex and pose unique challenges in a correctional setting.
