Which is NOT a type of citizenship?

Analyze the question: We need the option that is NOT a way of acquiring or a type of citizenship.

Concept: Under Nigerian law (the 1999 Constitution), citizenship is acquired in these ways:

1. By birth – being born in Nigeria to parents or grandparents who belong to an indigenous community.
2. By registration – for example, a foreign woman married to a Nigerian man, or persons of Nigerian descent, can apply to be registered.
3. By naturalization – a foreigner who meets residency, good character and other requirements is granted citizenship.
4. By honorary conferment – citizenship granted to distinguished persons as a mark of honour.

Marriage is traditionally treated as a route to citizenship, because it leads to registration. Many Nigerian Government textbooks list it as a type or mode of citizenship.

Check each option:

• A. Conferment – honorary citizenship, so it is a type.
• B. Indigenousness – this describes belonging to an ethnic community native to a place. It is a basis for claiming citizenship by birth, but it is not a distinct type or mode of citizenship in the way the others are.
• C. Marriage – commonly listed as a mode of citizenship.
• D. Naturalization – a recognised type.
• E. Registration – a recognised type.

Answer: The option that is not a type of citizenship is B. indigenousness.

Tip: Remember the standard modes with the phrase "BRNC-M": Birth, Registration, Naturalization, Conferment (honorary), and Marriage (often linked to registration). "Indigenousness" is a description of origin, not a mode of acquiring citizenship.
