The correct answer is B. Ethiopian language was not integrated in Geez language, as that language actually didn't even existed ever.
Geez is an extinct language belonging to the group of Southern Semitic languages. It was spoken in the Kingdom of Aksum, in the north of present-day Ethiopia.
The most important modern languages that descend from Geez are Tigrinya and Tigre. Other languages such as the Amharic or the Gurague are closely related to it, but they are not direct descendants of Geez.
