Step-by-step explanation:
European settlers were drawn to settle in America due to its geography, specifically the vast amount of available space. This is represented by option D - The space. The wide-open land offered opportunities for expansion and the establishment of new communities. Europeans sought to escape overcrowding and find new opportunities for wealth and a better life.
The availability of space in America meant that Europeans could establish new settlements and expand their territories.
