Which of the following best describes "Jus sanguinis"?

The term "Jus sanguinis," which is Latin for "right of blood," refers to the principle where an individual's nationality or citizenship is determined by their parents' nationality or citizenship rather than the place of birth. This means that if a person's parents are citizens of a particular country, that person is automatically granted citizenship of that country, irrespective of where they were born. This principle is commonly used by several countries around the world to define citizenship based on familial lineage.

In contrast, the other options describe different concepts related to citizenship. The first option pertains to "Jus soli" (right of soil), which is the principle granting citizenship based on the birthplace. The third option suggests a universal approach to citizenship that does not align with either jus sanguinis or jus soli. The fourth option addresses dual citizenship regulation, which is a separate legal matter that does not fall under the classification of jus sanguinis.
