Which group lists only Bantu communities of East Africa?

1. East Africa's inhabitants fall into four main language groups, of which the Bantu is one. 2. Kikuyu, Kamba, Baganda and Nyamwezi all belong to the Bantu group. 3. The Maasai, Luo and Kalenjin are Nilotes, not Bantu. 4. The Somali are Cushites, so any list including them is not purely Bantu. 5. Every wrong option here mixes in at least one Nilote or Cushite community, which is exactly what the item tests. _Source: NECTA CSEE 2023 History 012, Question 1: Multiple Choice Items, item (v)_
