Explanation:

- Option 3: Bukumatula

- Correct Answer

- This is the name given to the dormitory used by the Trobriand Islanders. Bronislaw Malinowski studied their culture in depth, noting the importance of the Bukumatula as a space where young people lived and interacted.

- Option 1: Ikhuichi

- This option does not relate to the Trobriand Islanders or Malinowski's work. It is not a term associated with their dormitories.

- Option 2: Aricha

- This also does not correspond to any known element in Malinowski's studies of the Trobriand Islanders. It is unrelated to their dormitory system.

- Option 4: None of the above

- This would only be correct if none of the terms matched the dormitory studied by Malinowski, but in this case, Bukumatula is the correct term.
