Which of the following conditions does not fulfill the definition of "both parents" in terms of citizenship?

• A. Both parents must be citizens
• B. At least one parent must be a citizen
• C. One parent must be a naturalized citizen
• D. Parent must be a legal guardian only

Answer: (D)

The choice that accurately represents a condition that does not fulfill the definition of "both parents" in terms of citizenship is one where the requirement is solely that the parent must be a legal guardian. In matters of citizenship, the concept of "both parents" typically refers to biological or adoptive parents who hold citizenship status. A legal guardian, although they may have custody or care responsibilities for a child, does not necessarily have a direct link to the child's citizenship status.

In contrast, both parents being citizens or one parent being a citizen are criteria that relate directly to citizenship transmission, while the requirement that one parent must be a naturalized citizen also fits this definition, as naturalized citizens hold the same citizenship rights as citizen by birth. Therefore, defining a parent solely as a legal guardian does not meet the requirements set forth in the context of citizenship rights and inheritance.
