Final answer:
Jacques Cartier and Giovanni da Verrazano sailed across the Atlantic from France to explore and claim land for France. Pedro Cabral was the first explorer to reach Brazil and claim it for Portugal, not Christopher Columbus, Ferdinand Magellan, or Jacques Cartier. The correct option is B.
Step-by-step explanation:
The explorers who sailed across the Atlantic from France to explore were Jacques Cartier and Giovanni da Verrazano. Both were commissioned by the French monarchy to find new routes and to establish French claims in the New World. Jacques Cartier claimed the mouth of the St. Lawrence Seaway for France, while Giovanni da Verrazano was looking for a northwest passage to India in 1532.
In relation to the first explorer to reach Brazil and claim it for the throne of Portugal, that distinction goes to Pedro Cabral. Christopher Columbus, although a significant figure in Atlantic exploration, claimed lands for Spain and did not reach Brazil for Portugal. Ferdinand Magellan circumnavigated the globe, but also did not claim Brazil for Portugal, and Jacques Cartier was involved in North American exploration.
