Tanzania's economy collapsed because of its experiment with A) socialism.

Explanation:

After its independence from Britain, Tanzania employed Ujamma a socialist point of view proposed by Julius Neryere their political leader at the time. The concept derived from socialism and the African culture of family. His proposal was the installation of one party in power, the institutionalization of economy and nationalization of some major economic sectors. The nationalization of development, guiding Tanzanian efforts to develop and become self-sufficient and the implementation of compulsory education among others.

However, the socialist approach he took didn't have the support of foreign investment, leading the nation to a low speed of development. Also, war with Uganda helped to the decline of the power because they weren't self-sufficient enough to exploit all their economies.

it was the first major victory for the colonists.
