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.
