Final answer:
The correct answer is c) welfare, as the 3 Gs in the Age of Exploration were God, glory, and gold, and welfare was not one of the primary motives.
Step-by-step explanation:
The 3Gs referred to in the Age of Exploration stand for God, glory, and gold. These were the primary motives for European countries, particularly Spain and Portugal, during the Age of Exploration. They wanted to spread Christianity (God), achieve fame and national prestige (glory), and accumulate wealth (gold).
Answering the question: Which of the following was not one of the 3 Gs in the Age of Exploration? The correct option is c) welfare, as welfare was not considered a driving motive during this period. The European explorers' motivations were not focused on the betterment of people's welfare but rather on spreading religion, achieving fame, and amassing wealth.
