A mobile phone is sold in Nigeria. The phone is assembled in Hungary, battery made in India, recharger made in China.

1. Is the mobile phone is a Nigerian product, import or export? Why?

The mobile phone is not a Nigerian product, but it is an import. Even though it was sold in Nigeria, it was assembled in Hungary and its components such as the battery and recharger were made in India and China respectively. Therefore, it does not belong to Nigeria's domestic production. Instead, it was brought in from other countries, making it an import.
