Answer:
c. Egyptian
Step-by-step explanation:
The content of the Rosetta Stone is written in three different languages, as the question says, in order of placement in the stone:
- Egyptian - the main language in Ancient Egypt, also known as Hieroglyphs writing. It was used among the priests and members of the religious group.
- Demotic - it was the common language and used among the people
- Greek - it was used in the political relations
The Rosetta Stone was deciphered by Jean-François Champollion in 1822. He was only able to do that because he found similarities in the Demotic and Greek languages. Then he created an alphabet for the Hieroglyphs, finally understanding the code.
