Option 1 -> Cuba has a different political system with its own leadership structure, and Claudia Sheinbaum was not elected there.
Option 2 -> Mexico elected Claudia Sheinbaum in 2024, making her the first female president and first person of Jewish heritage to lead the country.
Option 3 -> Vietnam follows a communist political system with different leadership positions, unrelated to Claudia Sheinbaum's election.
Option 4 -> Singapore has its own parliamentary system and prime minister, and this election did not occur there.
Hence, Option 2: Mexico -> Claudia Sheinbaum won Mexico's presidential election in June 2024 with approximately 60% of the vote, representing the Morena party, marking a historic milestone as Mexico's first female president and first leader of Jewish descent -> correct
