Answer:**Charles de Gaulle** commanded Free France against Nazi Germany during World War II.
Here's a brief overview of each individual mentioned:
1. **Charles de Gaulle**: As the leader of the Free French Forces, de Gaulle was a prominent figure in the resistance against Nazi Germany. After the fall of France in 1940, he fled to Britain where he established the Free French government in exile and rallied French forces to continue the fight against the Axis powers. He became the symbol of French resistance and played a crucial role in the liberation of France.
2. **Jean Lannes**: Lannes was a Marshal of France under Napoleon Bonaparte. He was a prominent military leader during the Napoleonic Wars but was not involved in the Second World War.
3. **Napoleon Bonaparte**: Napoleon was a French military leader and emperor who reigned in the early 19th century, long before World War II. His era was characterized by the Napoleonic Wars, not the conflict with Nazi Germany.
4. **Jean Moulin**: Jean Moulin was a key figure in the French Resistance during World War II, but he was not the commander of Free France. He worked to unify various resistance groups under the Free French banner and was instrumental in organizing resistance activities inside France.
Therefore, **Charles de Gaulle** is the correct answer as the leader who commanded Free France against Nazi Germany.
