Who is Ursula von der Leyen?

Ursula von der Leyen is indeed the 13th President of the European Commission, making this the correct answer. She took office on December 1, 2019, becoming the first woman to hold this position. As President of the European Commission, she is responsible for setting the political agenda and overseeing the work of the Commission, which is the executive branch of the European Union. This role includes proposing legislation, enforcing EU laws, and managing the EU's budget and policies.

The other roles mentioned, such as being a member of the German Parliament, Chancellor of Germany, or President of the European Council, do not accurately reflect her current position. While she has had a significant career in German politics, including serving as a Minister in various capacities, her leadership of the European Commission marks her prominent role in European governance.
