The correct answer is B) existed before other cultures were present in the region. 
<em>The Swahili coast developed its own unique culture that existed before other cultures were present in the region. </em>
The Swahili inhabited the African Great Lakes territories and spoke Swahili.  They originated from Bantu people, from Kenya and Mozambique. By the 8th century, they traded their products through the Indian Ocean, receiving the influence of cultures such as the Chinese and Arab. It is true that the Swahili coast developed its own unique culture that existed before other cultures were present in the region.
 
        
                    
             
        
        
        
Option A, Meroitic is the right answer.  
The Egyptian script in the 3rd century BC was replaced by a new indigenous alphabet, called the Meroitic. This script is associated with two alpha- syllabary scripts developed to write the KUSH-ite  (the language of the KUSH kingdom). The KUSH-ite language was written in two forms of Meritoic alphabet known as the  cursive and  Hierarchic. While Meroitic cursive was used for general record keeping, its Hieroglyphic was used for the religious or royal documents. Hence, this script was the unique achievement of the KUSH civilization.
