Which tool researchers decipher egyptian hieroglyphics? a. the pharaoh's stone b. the translation guide c. the epic of gilgamesh d. the rosetta stone

D.The Rosetta Stone.

Explanation:

A stone made of granodiorite stele was found in 1799 which came to be known as "The Rosetta Stone". It contains an inscription with three versions of a decree that was issued in Memphis. This inscription was from the Ptolemaic dynasty on behalf of King Ptolemy V Epiphanes.

This stone became the main tool for the researchers to use in their deciphering of Egyptian hieroglyphics. The top two of the three inscriptions on this stone were in Ancient Egyptian, in hieroglyphics and demotic script, while the third was written in Ancient Greek. It also enables researchers a new window to understand and learn about ancient Egyptian history.
