Who is the current Vice President of the United States?

The current Vice President of the United States is Kamala Harris, who made history by becoming the first woman, the first African American woman, and the first person of South Asian descent to hold this office. She serves under President Joe Biden, having been inaugurated on January 20, 2021. Her role involves not just performing ceremonial duties but also participating in national discussions on policies and representing the administration.

The other individuals mentioned in the choices have held different roles in American politics but are not currently in the position of Vice President. Sarah Palin served as the Governor of Alaska and was the Republican vice-presidential nominee in 2008; Michelle Obama served as First Lady and is known for her work on health and education but has not pursued political office since leaving the White House; and Hillary Clinton has been a former Secretary of State and was the Democratic presidential nominee in 2016, yet she is not in a vice presidential role. Understanding the current political context and the roles these individuals have played helps clarify why Kamala Harris is the correct answer.
