Final answer:
Tunisia does not use "Nkosi Sikelel' iAfrika" as part of their national anthem, unlike South Africa, Zambia, and Tanzania, which do.
Step-by-step explanation:
The country that does not use "Nkosi Sikelel' iAfrika" (Lord, Bless Africa) as or as part of their national anthem among the options provided is d) Tunisia. "Nkosi Sikelel' iAfrika" is part of the national anthems for South Africa, where it was combined with "Die Stem van Suid-Afrika" to form the current anthem after the end of apartheid, symbolizing unity and the diversity of languages and cultures in the country. It is also part of the national anthems of Zambia and Tanzania, being a symbol of political defiance and African liberation. However, Tunisia has its own national anthem, "Humat al-Hima", which is unrelated to "Nkosi Sikelel' iAfrika".
