How is the rosetta stone key to modern-day understanding of ancient egypt?

the rosetta stone outlined ancient egypt’s social hierarchy.
the rosetta stone allowed for the interpretation of hieroglyphs.
the rosetta stone contained a timeline of egyptian dynasties.
the rosetta stone provided a map of the pharaohs’ tombs.

The correct option is "The Rosetta Stone allowed for the interpretation of hieroglyphs."

The Rosetta stone is a fragment of an ancient Egyptian stela of granodiorite inscribed with a decree published in Memphis in the year 196 a. C. in the name of Pharaoh Ptolemy V. The decree appears in three different scriptures: the upper text in Egyptian hieroglyphs, the middle part in demotic script and the lower part in ancient Greek. Because it presents essentially the same content in the three inscriptions, with minor differences between them, this stone provided the key to the modern deciphering of Egyptian hieroglyphics. The stela was elaborated after the coronation of Ptolomeo V and a decree was registered to him that established the divine cult to the new governor, dictated by a congress of priests reunited in Memphis.
