Who was the famous queen of ancient Egypt known for her relationships with Julius Caesar and Mark Antony?

The famous queen of ancient Egypt known for her relationships with Julius Caesar and Mark Antony is Cleopatra. She was the last active ruler of the Ptolemaic Kingdom of Egypt and is often remembered for her intelligence, political acumen, and charisma. Cleopatra's relationships with these prominent Roman leaders were pivotal, both personally and politically, as they aimed to secure her power and influence in a tumultuous period marked by the transition of Rome from a Republic to an Empire. Her alliances played a significant role in the historical context of Hellenistic Egypt and Roman politics, and they ultimately contributed to her legacy as one of history's most intriguing figures.

The other choices represent notable figures but do not match the criteria. Nefertiti, while well-known, was not connected to Julius Caesar or Mark Antony. Hatshepsut was one of Egypt's most successful pharaohs but lived in a much earlier period and did not have relations with Roman leaders. Nephthys, a goddess in Egyptian mythology, is not a historical figure and thus is not relevant to the question.
