The correct statement that explains what happened during Álvar Núñez Cabeza de Vaca’s expedition in 1528 is:
He was shipwrecked near Galveston and survived only because the Karankawa people gave him food and shelter.
Cabeza de Vaca and his crew experienced a shipwreck on the Texas coast, and after struggling to survive, he was helped by the Indigenous Karankawa people.
