Based on the options provided and without seeing the specific map, the most logical conclusion about the development of transatlantic trade would likely be:
A) The demand for labor in North America drove trade.
This is because the transatlantic trade, particularly during the period of European colonization and the development of the plantation economy in North America, heavily relied on enslaved labor from Africa to meet the agricultural demands, especially in the Southern colonies. However, if your map specifically emphasizes natural resources, or the trade dynamics between continents, further context would be necessary to refine this conclusion. If the map prominently features natural resources from North America or Africa, other options may be more relevant.
