Clearly explain four ways a nigerian can lose his or her citizenship in a shorter term

A Nigerian can lose their citizenship in a relatively shorter term through the following four ways:

1. Voluntary Acquisition of Another Citizenship (for citizens by birth): A Nigerian citizen by birth who voluntarily acquires the citizenship of another country (other than by marriage) automatically ceases to be a Nigerian citizen from the date of acquiring the new citizenship.
2. Formal Renunciation: Any Nigerian citizen of full age and capacity who is also a citizen of another country can make a formal declaration renouncing their Nigerian citizenship. This is a direct, voluntary act.
3. Deprivation for Fraud or False Representation (for citizens by registration or naturalization): If it is discovered that a person obtained Nigerian citizenship by registration or naturalization through fraud, false representation, or concealment of material facts, their citizenship can be revoked.
4. Deprivation for Disloyalty (for citizens by registration or naturalization): A citizen by registration or naturalization can be deprived of their citizenship if they have shown disloyalty to Nigeria, such as by trading with an enemy country during a war in which Nigeria is engaged.
