What is the definition of individuals related by consanguinity or affinity?

The term "individuals related by consanguinity or affinity" refers specifically to those who are connected by blood (consanguinity) or by marriage or other close relationships (affinity). The definition of family encompasses both these forms of relationships. For instance, consanguinity includes parents, siblings, and extended relatives, while affinity covers relationships formed through marriage, such as in-laws. Therefore, the correct answer is family, as it comprehensively captures the essence of both blood relations and those linked through marital ties, accurately reflecting the meaning of the term in a legal and social context. Other choices like friends, acquaintances, and colleagues refer to social or professional relationships, which do not inherently include the legal or biological connections implied in the question.
