Nigeria's non-aligned policy means that she does not take sides in international issues based on ideological considerations. This policy is based on the principle of neutrality and non-alignment with any particular ideology or bloc, and instead seeks to maintain friendly relations with all nations based on mutual respect and cooperation. By adopting a non-aligned stance, Nigeria seeks to promote its own national interests, maintain its independence and sovereignty, and avoid getting involved in conflicts or alliances that do not directly benefit the country. Nigeria's non-aligned policy does not mean that it has nothing to do with superpowers, or that it avoids dealing with countries based on ideological leanings. Rather, it means that Nigeria seeks to maintain an independent foreign policy and engage with all nations on the basis of mutual benefit and respect, regardless of their political or ideological orientation. Therefore, the correct option is "not take sides in international issues based on ideological considerations".
